Your car broke down and the final bill was 261.50 the part that was replaced cost 99 and the charge for the mechanics labor is 6 5 per hour write an inequality to model this situation then solve the equation for the number of hours the mechanic worked on your car
1 answer:
Your inequality would be 261.50 less than or equal to 65x+ 99 now to solve this you would begin by isolating 65x you would do this by subtracting 99 on both sides. 162.50 less than or equal to 65x to get x alone [because thats what youre solving for] you need to divide by 65 on both sides. x= 2.5 Now you can check youre work 261.50 less than or equal to 65(2.5) + 99 youll get 261.50 less than or equal to 261.50
