You can buy 5 apples for $6.25 or 8 apples for $10.24. Which is the better deal? Explain.

8 apples for $10.24 as your getting more apples for almost the same price.

Step-by-step explanation:

$6.25 divided by 5 is $1.25 so that would be $1.25 per apple

$10.24 divided by 8 is $1.28 so that would be $1.28 per apple

5 apples for 6.25 dollars is the better deal.

Step-by-step explanation:

I set both deals as a ratio and cross multiplied them with X/1 to get how much each apple would cost per one apple. The first deal ended up being cheaper with 1.25 dollars per apple. The more expensive deal was 1.28 dollars per apple. Therefore 5 apples for 6.25 dollars is the better deal.

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
