An automobile dealership has found that for every 140 cars​ sold, 26 will be brought back to the dealer for major repairs. If the dealership sells 840 cars this​ year, approximately how many cars will be brought back for major​ repairs?

Answer 1

First, we need to calculate the ratio of cars brought back for major repairs to the total number of cars sold.

26 cars brought back for major repairs out of 140 cars sold is equivalent to x cars brought back for major repairs out of 840 cars sold.

26/140 = x/840

Multiply both sides by 840:

x = (26/140) * 840
x = 154.286

So, approximately 154 cars will be brought back for major repairs when the dealership sells 840 cars.
