Question

A family goes to a restaurant. When the bill comes, this is printed at the bottom of it:

Gratuity Guide For Your Convenience:
15% would be $4.89
18% would be $5.87
20% would be $6.52
How much was the price of the meal?(Round to the nearest cent)

Answer 1

Explanation:

We can start by assuming that the price of the meal is x dollars. Then, we know that:

15% of x is equal to $4.89

18% of x is equal to $5.87

20% of x is equal to $6.52

We can set up three equations using these statements:

0.15x = 4.89

0.18x = 5.87

0.20x = 6.52

Solving for x in each equation, we get:

x = 4.89 / 0.15 = 32.60

x = 5.87 / 0.18 = 32.61

x = 6.52 / 0.20 = 32.60

Since all three equations give us a value of x that is very close to 32.60, we can assume that the price of the meal was $32.60, rounded to the nearest cent.
