for tip. What is the total cost including the sales tax and tip? (HINT: regular price + sales
tax + tip = total cost

Answer 1

$49.53

Step-by-step 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

prize = $39

sales tax = $7

total cost = x

tip = 20% of the tax
