A new hard drive costs $225, plus $40 per hour for labor. The linear equation y=40x + 225 gives the cost y in dollars for x hours of labor. If Jane has $385 to spend on computer repairs, what is the maximum number of hours the computer technician can work? *

Answer:

4 hours

Explanation:

y = 40x + 225

***The value of y here is 385 since it is the amount of money that Jane can spend on computer repairs.

385 = 40x + 225

385 - 225 = 40x

160 = 40x

160 = 40x

40 40

4 = x
