You build and sell toy cars $36 each. So far you have built 24 toy cars how many more toys cars will you have to build and sell to earn 1,620?

Hello!

We know that you sell each toy car for $36.00 and you've made 24 so far.

Multiply the price of each car by how many you've made so far.

36 * 24 = 864

This means you'll make $864.00 when you sell 24 cars.

Since you want to earn $1620.00 and you've already got $864.00 of it, subtract the money you'll get from 24 cars from how much money you want to earn.

1,620 - 864 = 756

Finally, divide this by the cost of each car.

756 : 36 = 21

So, you'll have to build and sell 21 more cars to earn $1,620.00.
