Q:

Jermaine had dinner at his favorite restaurant. If the sales tax rate is 5% and the sales tax on the meal came to $2.00, what was the total cost of the meal, including sales tax and a 15% tip A.$52.50 B.$40.00 C.$48.00 D.57.00

Accepted Solution

A:
Sales tax = 5%
Sales Tax = $2
⇒ 5% is equal to $2

------------------------------------------------------------
Find 1%:
------------------------------------------------------------
5% = $2
1% = $2 ÷ 5
1% = $0.40

------------------------------------------------------------
Find 100% (Cost of the meal):
------------------------------------------------------------
100% = $0.40 x 100
100% = $40

------------------------------------------------------------
Find tips:
------------------------------------------------------------
15% tips = 15% x $40
15% tips = 0.15 x 40
15% tips = $6

------------------------------------------------------------
Find total cost:
------------------------------------------------------------
Total cost = $40 + $2 + $6 = $48

------------------------------------------------------------
Answer: $48
