Calculating Earnings for Washing Cars

Let's assume that you earn $35 for washing one car. This is a simple problem that can be solved using basic arithmetic operations. To calculate the earnings for washing 3 cars, we need to multiply the earnings for one car by 3.

Formula for Calculating Earnings

The formula for calculating earnings for washing 3 cars is:

Earnings for 3 cars = Earnings for 1 car x 3

Substituting Values

Now, let's substitute the value of earnings for one car, which is $35, into the formula.

Earnings for 3 cars = $35 x 3

Calculating Earnings

To calculate the earnings for 3 cars, we need to multiply $35 by 3.

$35 x 3 = $105

Conclusion

Therefore, if you earn $35 for washing one car, you will earn $105 for washing 3 cars.
