Question

The inequality 2 p ≤ 18 can be used to determine how many pounds of apples at $2.00 per pound, p, you can buy while spending $18.00 or less. What is the greatest number of pounds of apples you can buy?

A) 9 pounds
B) 16 pounds
C) 20 pounds
D) 36 pounds

Answer 1

So we know we don't want to exceed 18 dollars. 

So what we want to know is how many times can 2 dollars go into 18 dollars. 

We would do $18/2 = 9$

Now the answer is 9, so we know we can buy 9 pounds of apples without going over 18 dollars.
