Question

Dominique used the inequality below to find the maximum number of sweatshirts she could purchase with her savings.

32 x < 300

What is the greatest number of sweatshirts Dominique can purchase?

Answer 1

We just have to find the closest number that can be multiplied by 32 and still be under 300. Do this by following this step:

Divide by 32 on both sides.

x < 9.375

We can't buy 9.375 sweatshirts though, and we can't add more decimals or it will go over 300, so you round down to 9.

Dominique can buy 9 sweatshirts without going over $300!
