The total cost of the dinner is $82.2
<h3>How to calculate the total cost of the dinner ?</h3>
Janelle and some friends went out to dinner
The cost of the meal was $68.50
They left a 20% tip
The first step is to multiply the 20% tip by the amount
20/100 × 68.50
= 0.2 × 68.50
= 13.7
Next step is to add 13.7 to the cost of the meal
= 13.7 + 68.50
= 82.2
Hence the total cost of the dinner is $82.2
