Question

The sales of new cars at a dealership increased by 3% this year to 360. Find the number of sales the previous year.

Answer 1

350.

Explanation:

Let x be the number of sales previous year.

We have been given that the sales of new cars at a dealership increased by 3% this year to 360.

We need to find x such that x plus 3% of x equals 360. We can represent this information in an equation as:

`x+((3)/(100)*x)=360`

`x+0.03x=360`

`1.03x=360`

Upon dividing both sides of our equation by 1.03 we will get,

`(1.03x)/(1.03)=(360)/(1.03)`

`x=349.51456\approx 350`

Therefore, the number of sales the previous year was 350.
