Question

Let the price of a meal at a restaurant be p. The tax and tip on the meal are generally a percentage of the meal's price. The total cost of the meal is its price plus tax plus tip. Write an expression for the total cost of a meal where the tax is 8% and the tip is 15%.

a) Total Cost = p + 0.08p + 0.15p
b) Total Cost = p + 0.23p
c) Total Cost = 0.08p + 0.15p
d) Total Cost = p + 0.23

Answer 1

The expression for the total cost of a meal can be written as p + 0.08p + 0.15p, where p is the price of the meal. This expression represents the price of the meal plus 8% of the price for tax and 15% of the price for tip.

Step-by-step explanation:

The expression for the total cost of a meal can be written as:

Total Cost = p + 0.08p + 0.15p

This means that the total cost of the meal is equal to the price of the meal (p) plus 8% of the price (0.08p) for tax plus 15% of the price (0.15p) for tip.
