Answer:
It took 5 hours to repair the car
Step-by-step explanation:
An auto repair shop charged a customer $349 to repair a car.
The bill listed $99 for parts and the remainder for labor.
The cost of labor is $50 per hour. If the number of hours it took to repair the car is x, then:
99 + 50x = 349
To find the number of hours it took to repair the car, we need to find x:
50x = 349 - 99
50x = 250
x = 250 / 50 = 5 hours
It took 5 hours to repair the car.
For number 9, you know that it makes 40 copies every five minutes. All you have to do is divide 40 by 5.
40 ÷ 5 = 8
It makes 8 copies every minute.
Your chart can also help you check your answer. It says that it makes 96 copies every 12 minutes and it makes 104 copies every 13 minutes. So multiply 8 by 12 to check it and 8 by 13.
8 • 12 = 96
8 • 13 = 104
Since those answers match up with the chart, it must be correct.
The photocopier makes 8 copies every minute. Hope that helps!
