Question
Amir has $50 to spend. She wants to buy a CD for $20 and spend the rest on jewelry sets which cost $8 each. Write an inequality and then solve for the number of jewelry sets she can buy.

1. User Answers Equanimity
X = The amount of cd's
Y = Jewelry sets
X + Y = 50
X + 8y<_50
20 + 8Y<_50
Subtract 20 from both sides.
8Y<_30
Divide by 8 on both sides
Y<_3.75 (3 total)
She can buy 3 jewelry sets.
