Homework Help: math

Amanda is decorating her new home and wants to buy some house plants. She is interested in three types of plants costing $4, $8, and $20. If she has budgeted exactly $96 for the plants and wants to buy exactly 12 of them, what are her options? Let x be the number of $4 plants, y the number of $8 plants, and z the number of $20 plants.

here's one option:
z = 2
y = 4
x = 6

$20 * 2 = $40
$8 * 4 = $32
$4 * 6 = $24
$40 + $32 + $24 = $96
2 + 4 + 6 = 12
