**Reiny**, Saturday, November 7, 2009 at 8:19amFirst you must define your variables.

In full sentence form define

apples ---> a

melons ---> m

then Cost = 3.75a + 1.5m

second equation:

3.75a + 1.5m ≤ 30

multiply this equation by 4

15a + 6m ≤ 120 , dividing by 3

5a + 2m ≤ 40

2m ≤ 40 - 5a

For m to be a whole number, the right side of the above statement has to be even, so a must be an even number

0 ≤ a ≤ 8

so give a values of 0, 2, 4, 6, and 8
