Answer: 24
Step-by-step explanation:
Let the total number of problems be x.
After 15 minutes, [tex]x-\frac{1}{4}x=\frac{3}{4}x[/tex] problems are left.
After another 15 minutes, [tex]\frac{3}{4}x\left(1-\frac{1}{3})=\frac{3}{4}x\left(\frac{2}{3} \right)=\frac{1}{2}x[/tex] problems are left.
This is equal to 12, meaning x = 24.

Santiago and some friends are going to the movies. At the theater, they sell a bag of popcorn for $5.75 and a drink for $3.50. How much would it cost if they bought 4 bags of popcorn and 8 drinks? How much would it cost if they bought pp bags of popcorn and dd drinks?
Answers
Answer:
$23 for popcorns and $28 for drinks the sum is $51
Step-by-step explanation:
The total cost of buying 4 bags of popcorn and 8 drinks is $51.
What is the meaning of the term “cost”?A cost is the worth of money that has been expended to produce something or provide a service and is therefore no longer available for use in production, research, retail, and accounting.
In the case of an acquisition cost, the money spent on the acquisition is considered the cost. All costs associated with obtaining and preparing materials for sale are referred to as "Cost of Purchase," or “Cost of buying,” respectively.
As per the available information,
Selling price of a single popcorn bag is $5.75.
Selling price of a single drink is $3.50.
Value or total amount of cost will be calculated against 4 bags of popcorn and 8 drinks.
Cost of popcorns = 4 × 5.75 = 23
Cost of drinks = 8 × 3.50 = 28
23 + 28 = 51
Therefore, total cost of buying 4 bags of popcorn and 8 drinks is $23 for popcorns and $28 for drinks, the sum is $51

Each side of a square patio is 10.5 feet. The patio is made up of 1.5 foot by 1.5-foot square stones. What is the number of stones in the patio? Look at the solution below.
Does it include all the steps needed to solve the problem? Explain
10.5 x 10.5 = 110.25
110.25 ÷ 1.5 = 73.5
Answers
Answer:Yes
Step-by-step explanation:
The solution provided is complete and includes all the steps needed to solve the problem.
The first step is to calculate the area of the square patio by multiplying the length of one side by itself:
10.5 x 10.5 = 110.25.
The second step is to divide the area of the patio by the area of each individual stone to determine the number of stones needed:
110.25 ÷ 1.5 = 73.5.
Since it is not possible to have a fraction of a stone, the answer should be rounded up to the nearest whole number, which is 74.
Therefore, there are 74 stones on the patio.
