Four siblings have a dog walking business. The table shows the hours worked by each sibling. Each sibling earns $25.50 per hour and the total number of hours worked is represented by 10h+15 , where h represents the number of hours Michael worked.
Martin 2.5h+3

The algebraic expression is the combination of variable and constants with some mathematical operation between them. The Earning of the four siblings are $357, $244.8, $112.2 and $790.5 respectively.
What is an Algebraic expression?An algebraic expression can be obtained by doing mathematical operations on the variable and constant terms.
The variable part of an algebraic expression can never be added or subtracted from the constant part.
Given that,
The earning of the siblings per hour is $25.50.
Total number of hours worked is 10h + 15.
As per the problem the value of h can be found by equating the total number of hours to the sum of hours worked by each sibling as given in the table as follows,
2.5h + 3 + 4(h - 2) + h + 31 = 10h + 15
⇒ 2.5h + 3 + 4h - 8 + h + 31 = 10h + 15
⇒ 7.5h + 26 = 10h + 15
⇒ 2.5h = 11
⇒ h = 11 / 2.5
⇒ h = 4.4
Thus, the earning of each sibling can be calculated by substituting h = 4.4 in their working hour and multiplying it by $25.50 as follows,
Earning of Martin is given as,
(2.5 × 4.4 + 3) × $25.50 = $357
Earning of Emilio is given as,
4(4.4 − 2) × $25.50 = $244.8
Earning of Michael is given as,
4.4 × $25.5 = $112.2
Earning of Mario is given as,
31 × $25.50 = $790.5
Hence, the earnings of the four siblings are as Martin : $357, Emilio : $244.8, Michael : $112.2 and Mario : $790.5.

B
4.7x+7.9
C
−12.1x+7.9
D
12.1x+7.9
Answers
Step-by-step explanation:
so we know that
(8.4x+2.9)+(−3.7x+5)= 4.7x+7.9
so we need an equivelant to 4.7x+7.9
A. −4.7x+7.9= -1/10x(47x-79)
B.=4.7x+7.9=1/10x(47x+79)
C.−12.1x+7.9=-1/10x(121x-79)
D.12.1x+7.9=1/10x(121x+79)
So the answer would be B!

Jeremy bought a $60 pair of sneakers on sale for 15% off. Then, he used a coupon that gave him an additional 10% off. Can Jeremy find the cost of the sneakers by adding the percents?
by finding 25% off of $60, and
by finding 15% off of $60, and then subtracting 10% from that cost.
Complete the explanation.
25% off of $60 is equal to $
.
15% off of $60, then subtracting 10% from that cost, is equal to $
.
Are the two total costs equal? Enter yes or no.
Answers
Answer: No
Step-by-step explanation: you have to subtract 60$ and 15% and then subtract 45$ and 10%. Equals 35$ the total cost.
$51 - 10% is $45.90 (10% of $51 is 5.10)
No store can combine two coupons to give you higher percentage of discount . So he will end up paying $45.90 when used both coupons.
