$47.4

prize = $39

sales tax = $7

total cost = x

tip = 20% of the tax

Answer:

$49.53

Explanation:

Convert  7 %  to a decimal.

  • 0.07  x 39

Multiply  0.07  by  39 .

  • 2.73

Repeat, but with 20%.

  • 7.8

Add the tax and tip to the original price:

39 + 2.73 = 41.73

41.73 + 7.8 = $49.53
