Preston has a car washing business. Last year he washed 20 cars a week. This year, he washed 1,200 cars. How many more cars did

marishachu [46]

Answer:

160 cars

Step-by-step explanation:

The computation of the number of more cars he washed this year is given below;

Last year, he washed 20 cars a week so on yearly basis he washed

= 20 cars × 52 weeks

= 1,040 cars

And, this year he washed 1,200 cars

So, the number of more cars he washed this year is

= 1,200 cars - 1,040 cars

= 160 cars
