Question

. Lightning Lucy’s burnable CDs are on sale this

month for 10% off regular prices. If a pack of 10
blank CDs normally costs $15, how much do you
save per CD?
Original unit cost of CDs = $_________ per CD
10% of original cost = $_________
Original cost minus the 10% discount = $_______
Discounted unit cost of CDs = $_______ per CD
Subtract the two unit costs to find
how much saved per CD = $_________​

Answer 1

Original Cost = $1.50 per CD

Discount = $1.50

Discounted Cost = $13.50

Discounted Cost = $1.35 per CD

You Saved = $0.15 per CD

Explanation:

$15/10CDs = $1.50

$15x10% = $1.50

$15-$1.50 = $13.50

$13.50/10CDs = $1.35

$1.50-$1.35 = $0.15
