Answer 1

Question1
I am guessing the price of the cd was 16.99 and with tax it came to 18.26

let the sales tax = x% x 16.99x
then on price of 16.99, tax = ------ * 16.99 = --------- = 0.1699x
100 100

then final/bill amount = 16.99 + 0.1699x

ATQ 16.99 + 0.1699x = 18.26
=> 0.1699x = 18.26 - 16.99
=> x = 1.27/0.1699
=> x = 7.47 or 7.5

so sales tax was 7.5%

Answer 2

2.The sales tax of a picture frame came to $1.32 if the sales tax rate is 5.5 % , what was the price of the frame?

Let the price of the frame = $ x
then sales tax is 5.5% of x = 5.5/100 * x = 5.5x/100

5.5x
ATQ, ------- = 1.32
100
1.32 * 100 132
=> x = ----------- = -------- = 24
5.5 5.5

so the price of the frame was $ 24
