Leokris [45]

Answer:

His total bill including the tip = $39.6

Step-by-step explanation:

Christopher has breakfast at a cafe and the cost of his meal is $36.00

Because of the service, he wants to leave a 10% tip. This means that he would be paying more than the original cost of the meal. The cost of tip would be determined by multiplying the original cost of the meal by 10%. This becomes

Cost of tip = 10/100 × 36.00 =

0.1× 36.00= $3.6

His total bill including the tip would be sum of the cost of the original bill + cost of the tip. It becomes

36.00 + 3.6 = $39.6
