Answer 1

Audrey has $120 to spend on a tennis racket and lessons. The racket costs $45 and the lessons cost $15 per hour. Define a variable. Then write and solve a equation to find how many hours of lessons she can afford.

Part A Define a variable.

Let x represents the racket and let y represents the lessons

Part B Write an equation to find how many hours of lessons she can afford.

45 x + 15 y = 120

Part C Solve the equation to find how many hours of lessons she can afford.​

Given 45 x + 15 y = 120

when x = 2 , y =2 ( 2 hours for racket and 2 hours for the lessons).

45 ( 2 ) + 15 ( 2 ) = 90 + 30 = 120.
