dezoksy [38]
First calculate what the coupon does for Camille
so multiply %20 by the cost or .2(47.99)=9.598 which rounds to  9.60 meaning she still paid $38.39
Then calculate sales tax by multiplying her clearance price by %6 and adding it on the cost
.06(38.39)= 2.3034 which rounds to $2.30 in tax.
Add that onto the clearance price 38.39+2.30=$40.69
So her total cost was $40.69

change both the fractions to improper fractions. the area will be 147/4 , and the width will be 9/2 . with both of these you may now divide, (147/4) / (9/2)

remember to use the KCF when dividing fractions.

147 * 2 = 294

4 * 9 = 36

your new fraction will be 294/36 .... which it is also 8 1/6
