Sarah has a credit card balance of $9,450 with an APR of 17%. With her current budgeted payment, Sarah will be able to pay off this debt in 36 months. But Sarah’s best friend just invited her to spend two months in Europe with her in 9 months. Wanting to have her credit card balance paid off before she goes to Europe, Sarah decides to take on a second job. What additional monthly income will Sarah need in order to pay off her credit card in 9 months?

Sarah needs an additional monthly income of $1125.77 to pay off her credit card in 9 months.

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

Using the information given,

We can find the current monthly payment Sarah is making using the formula for the present value of an annuity:

[tex]PMT = PV \times r \times (1 + r)^n / [(1 + r)^{n - 1}][/tex]

where PV is the present value (balance), r is the monthly interest rate (APR/12), and n is the number of months (36).

PMT.

[tex]= 9450 \times 0.17/12 \times (1 + 0.17/12)^{36} / [(1 + 0.17/12)^{36} - 1][/tex]

= $338.48

To pay off the balance in 9 months, Sarah needs to increase her monthly payment.

Let's call this additional payment x.

Then, we have:

[tex]9450 \times 1.17^{9/12} = (338.48 + x) \times ((1 + 0.17/12)^{9 - 1}) / (0.17/12)\\[/tex]

Solving for x, we get:

x = $1125.77

Therefore,

Sarah needs an additional monthly income of $1125.77 to pay off her credit card in 9 months.

Answers

Answer:

Step-by-step explanation:

let's solve :

let's take

[tex]2 {}^{2x} = y[/tex]

now,

[tex]{(2{}^{2x} )} {}^{2} - 20(2) {}^{2x} + 64 = 0[/tex]

[tex]y {}^{2} - 20y + 64 = 0[/tex]

[tex]y {}^{2} - 16y - 4y + 64 = 0[/tex]

[tex]y(y - 16) - 4( - 16) = 0[/tex]

[tex](y - 16) (y - 4) = 0[/tex]

[tex]y = 16 \: \: or \: \: y = 4[/tex]

if y = 16, then :

[tex]2 {}^{2x} = 16[/tex]

[tex] {2}^{2x} = 2 {}^{4} [/tex]

[tex]2x = 4[/tex]

[tex]x = 2[/tex]

and if y = 4 :

[tex] {2}^{2x} = 4[/tex]

A 9-inch candle burns down in 12 hours. After how many hours will it have burned
3 3/8 inches?

Answers

Answer:

4.5

Step-by-step explanation:

Use a proportion.

3 3/8 = 3.375

9 inch is to 12 hours as 3.75 inches is to x hours.

9/12 = 3.375/x

3/4 = 3.375/x

3x = 4 * 3.375

x = 4 * 1.125

x = 4.5

Answer: 4.5 hours

Using rate if a 9-inch candle burns down in 12 hours, the amount of hours it have burned 3 ³/₈ inches is 4 ¹/₂ h

What is a rate?

Rate is the amount per unit time of a substance

Since a 9-inch candle burns down in 12 hours. To determine after how many hours will it have burned 3 ³/₈ inches, we proceed as follows.

First, we calculate the rate at which it burns which is given as r = Length of candle/time

Since

Length of candle = 9 in andtime = 12 hours

Substituting the values of the variables into the equation, we have that

r = Length of candle/time

r = 9 in/12 h

r = 3/4 in/h

To determine how many hours it would have burned 3 ³/₈ in, we have that

rate, r = Length/time

time = Length/rate

Since

Length = 3 ³/₈ in = 27/8 in andrate = 3/4 in/h

Substituting the values of the variables into the equation, we have that

time = Length/rate

= 27 in/8 ÷ 3/4 in/h

= 27/8 in × 4/3 h/in

= 9/2 h

= 4 ¹/₂ h

So, it will have burned for 4 ¹/₂ h

Step-by-step explanation:

We first would start with the last thing, the $38.50 Lisa has left! From reading the word problem, we can tell that she had another $38.50 she spent on a radio.She spends $7.20 (ring) + $1.95 (battery) before this and gives her mom $30.

All of these are subtractions from the initial amount:

x - 1.95 - 30.00 - 7.20 - 38.50 = 38.50

x - 77.65 = 38.50

x = $116.15

The length of a rectangle is 3 inches more than its width. if the perimeter is 42 inches, find the dimensions of the rectangle

Answers

Answer:

length = 12

width = 9

Step-by-step explanation:

Let w= width of rectangle

length = w + 3

2w + 2(w + 3) = 42

2w + 2w + 6 = 42

4w = 36

w = 9 ( width of rectangle)

width = 9 inches

length = 9 + 3 = 12 inches

A flat fee of $15.25 plus $3.45 per pound of supplies ordered is added to the bill to cover the shipping cost.The teacher budgets $49.75 for the shipping cost.Which list of values best represents the entire domain for shipping, f(x), as a function of the number of whole pounds of school supplies the teacher can order, x?

Answers

The domain of a function is the set of possible input value, the function can take.

The domain is [0,10]

The given parameters are:

[tex]Flat\ Fee = 15.25[/tex]

[tex]Rate = 3.45[/tex]

So, the function f(x) is:

[tex]f(x) = Flat\ Fee + Rate \times x[/tex]

[tex]f(x) = 15.25 + 3.45 \times x[/tex]

[tex]f(x) = 15.25 + 3.45x[/tex]

Because x represents the number of orders, the value of x cannot be negative.

The teacher budgets $49.75.

This means that: f(x) = 49.75

So, we have:

[tex]49.75 = 15.25 + 3.45x[/tex]

Collect like terms

[tex]49.75 - 15.25 = 3.45x[/tex]

[tex]34.5 = 3.45x[/tex]

Divide both sides by 3.45

[tex]10 = x[/tex]

Rewrite as

[tex]x = 10[/tex]

Hence, the domain is [0,10]
