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

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

So the total cost of the meal = Cost of the meal + Gratuity charges

So the total cost is the third option 1.18p.
