Question

Lucas bought some equipment for $37.38. The price he paid included a sales tax of 5%

What was the price of the equipment before the tax was added

A: $35.60

B:$ 36.33

C: $37.33

D $39.25

Answer 1

So, We Must Set Up A Proportion.
X 5
-------- = ------
37.38 100
100X = 37.38*5
100X = 186.9
--------------------
100 100
X = 1.86
37.38-1.86 = 35.60. So, The Answer Is A.
