Question

A baseball team wants to collect at least 160 cans of food for an upcoming food drive. Team members brought 42 cans of food on Monday and 65 cans of food on Wednesday. Write and solve an inequality to describe how many cans of food the team must collect on Friday to make or exceed their goal.

Answer 1

If they collect 65 on Monday, 42 on Wednesday and the rest on Friday, then we can write it down as:

65 + 42 + x ≥ 160
107 + x ≥ 160 / - 107 (both sides)
x ≥ 53

So the team needs to collect at least 53 cans on Friday.

Answer 2

`42+65+x≥160`

`x≥53`

Explanation:

IF the baseball team wants to collect at least 160, it means they want to collect 160 or more cans. If they brought 42 cans on Monday and 65 cans on Wednesday, let x be the amount of cans they must bring on Friday.

∴

`42+65+x≥160`

we can solve for x:

`107+x≥160`

`x≥53`

Therefore they have to bring 53 or more cans to ensure they collect atleast 160
