1. the cost of 5 squash and 2 zucchini is $1.32. three squash and 1 zucchini cost $0.75. find the cost of each vegetable.

Squash = s
zucchini = z

5s+2z = 1.32 ---(1)
3s+z = 0.75 (2)

2*(2); 6s+2z = 1.50 ---(3)
(3)-(1); s = 1.50-1.32= 0.18
then 3s + z = 0.75
3(0.18) + z = 0.75
0.54 + z = 0.75
so z = 0.75 - 0.54 = 0.21

so that the cost of squash is $0.18 and the cpst of zucchini is $0.21
