joe wants to spend 70. dollars at most and has 60 cu inches of space left in his soldier's care package. candy costs $7 and takes up 3 cu inch of space phone cards cost $5. and take up 15 cu in. of space.

Is this correct? if not please change it or tell me how ??? thanks ann

1. write a system of 4 inequalities that model his possible purchases.

Let x = # of candy and y = # of phone cards.

I wrote 7x + 5y <= 70

3x + 15y <= 60

x<= 10 (limited money 10 x $7 <= 70)

y <= 4

limited space (4 x 15 cu in < = 60)
