Question

raina bought 5 cds that were each the same price. including sales tax, she paid a total of $81.50. each cd had a tax of $0.80. what was the price of each cd before tax?

Explanation:

Step1: Calculate total tax for 5 CDs

Each CD has a tax of $0.80, so for 5 CDs, total tax is $0.80\times5$.
$0.80\times5 = 4$

Step2: Find total price of 5 CDs before tax

Total amount paid including tax is $81.50. Subtract total tax from this to get total price before tax: $81.50 - 4$.
$81.50 - 4 = 77.50$

Step3: Calculate price of each CD before tax

Divide total price before tax by number of CDs (5) to get price per CD: $\frac{77.50}{5}$.
$\frac{77.50}{5} = 15.50$

Answer:

15.50
