Question

A St. Louis Cardinals hat costs $18. If there is 8% sales tax, what is the total cost of the hat including tax?

Answer 1

Answer:

$19.44

Step-by-step explanation:

Hat cost = $18

Sales Tax= 8%

Total cost= ?

New value : Old value

(100+8)108 : 100

               x : $ 18

x multiply by 100 = 18 multiply by 108

x= $\frac{18x108}{100}$ [simplify]

x=$\frac{486}{25}$

x=19.44 $
