PLEASE HELP ASAP!!!!!
Suppose you need to get the dent in your car repaired. You see the ads above in the newspaper. Your father, who knows a bit about cars, said it would take no more than 3 hours for the repair person to fix your car. How do you determine where you should take your car to get it repaired? 1. Write an equation for each repair shop to represent the total cost of a car repair as a function of the number of hours worked.

Let x = number of hours worked Let y = total cost to you

Mike's repair shop:
Amy's repair shop:

2. Now, use the substitution or elimination method to find the point of intersection.

Respuesta :

mike charges 100 dollars service charge plus 65 dollars per hour.  

amy charges 40 dollars service charge plus 80 dollars per hour.  

the cost to repair from mike is 100 + 65 * x.  

the cost to repair from amy is 40 + 80 * x.  

let x = 3 and you get:  

the cost to repair from mike is 100 + 65 * 3 = 295 dollars.  

the cost to repaid from amy is 40 + 80 * 3 = 280 dollars.  

as long as the time to repair is 3 hours or less, the cost to repair will be cheaper from amy.
