Question

A set of speakers costs $22 and songs cost $1.25 each. The sales tax rate is 7.5%. The expression 0.075(22 + 1.25s) can be used to determine the amount of sales tax due on the entire purchase. Expand the expression and round to the nearest hundredth.

Answer 1

1.65 + 0.09s

Explanation:

Cost of speaker = 22

Cost per song = $1.25

Sales tax = 7.5%

Sales tax due on entire purchase :

0.075(22 + 1.25s)

1.65 + 0.09375s

To the nearest hundredth :

1.65 + 0.09s
