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 Answer

  • 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.
