Question

Amy and Dan are pastry chefs. Amy charges $25 for each order, and $15 per hour. Dan charges $10 for each order, and $20 per hour. What is the number of hours that would result in the same cost from both chefs?

Answer 1

3 hours

Explanation:

let x = # of hours

Amy: y = 25 + 15x

Dan: y = 10 + 20x

Set the expressions equal to each other and solve for x

10 + 20x = 25 + 15x

20x = 15 + 15x

5x = 15

x = 3
