When Erik solved this problem, he got 5/2 of a mile for his answer

4

Step by-step explanation: 4 cans for 3 dollars. Since this only costs 1$ more than the possible prices of the 4 cans then that's the answer.

In shorter terms; it's like 1 can cost 2 dollars on the 3 for 4 deal, and 1 can cost 3 dollars on the 9 for 12 deal, find this out by subtracting 9 from 12 and subtracting 3 from 4

y > 1/3x

y < = -x + 4

hope this : )
