Peter used a $5 gift card to help pay for his lunch. After adding a 15% tip to the cost of his meal, Peter still had to pay $2.36. How much did his meal cost?

Question

solve multi step equations

 

Answer 1

Let P be the price of the meal.

 

With the tip he paid P + .15 P = 1.15P = 5 + 2.36 = 7.36

 

The price of the meal is P = 7.36/1.15 = $6.40
