Answer:
$142.425
Step-by-step explanation:
Given:
A sports store is having a sale on skates, a pair originally cost is $135.
The sales tax is 5.5%
Question asked:
What is the total cost ?
Solution:
To find the total cost of a pair of skates, first of all we will find sale tax amount and then simply add the original cost and sale tax amount.
Original cost of a pair of skates = $135
Sales tax = 5.5%
Sales tax amount = [tex]5.5\% \ of\ 135[/tex]
[tex]=\frac{5.5}{100} \times135\\\\ =\frac{742.5}{100} \\ =\$7.425[/tex]
Total cost = Original cost + sale tax amount
= $135 + $7.425
= $142.425
Therefore, the total cost of a pair of skates at a sports store is $142.425
