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 [tex]= \frac{18}{100} (p) = 0.18p.[/tex]
So the total cost of the meal = Cost of the meal + Gratuity charges [tex]=p + 0.18p = 1.18p.[/tex]
So the total cost is the third option 1.18p.
