Question

A restaurant charges an automatic gratuity of 18% on tables with more than 6 people. A party of 8 had a bill of p. Which expression can be used to find the total cost of the meal with the gratuity?
0.18p
0.82p
1.18p
18.00p

Answer 1

The expression 1.18p can be used to find the total cost of the meal with gratuity.

Step-by-step explanation:

Step 1:

If there are more than 6 people, the restaurant charges an automatic gratuity of 18%.

Since there are 8 people this charge will also be applied here.

If the bill amount is p and 18% of p is added, the options 0.18p and 0.82p cannot be the total cost of the meal.

Step 2:

We need to determine how much 18% is in terms of p.

18% of p $= \frac{18}{100} (p) = 0.18p.$

So the total cost of the meal = Cost of the meal + Gratuity charges $=p + 0.18p = 1.18p.$

So the total cost is the third option 1.18p.
