Answer:
10 CDs
Step-by-step explanation:
First, we need to find out how much she spent in total.
365 - 185 = 180
Okay, we now know that Holly spent 180 off of her gift card in total. Now we need to find out how many CDs she purchased by spending that amount of money.
180 ÷ 18 = 10
Let's check our math.
18 × 10 = 180
So our answer is Holly bought 10 CDs.
Answer:
The number of CDs that she purchased is 10
Step-by-step explanation:
Let x represent the number of CDs that she purchased.
Holly had a gift card with a $365 balance. She bought several cds that cost $18 each. This means that the cost of x CDs would be 18×x = $18x.
After the purchase,her gift card balance was 185
This means that
365 - 18x = 185
Subtracting 365 from the left hand side and right hand side of the equation, it becomes
- 18x + 365 - 365 = 185 - 365
- 18x = -180
18x = 180
x = 180/18
x = 10
