Question

If the price of a car is $3,500 and the percent of the down payment is 10%, how much is the down payment, not figuring in tax?

Answer 1

Step-by-step explanation

To solve this kind of exercise, we must recall the percentage formula. It says that the y% of x, defined as z, is given by

`z=(y)/(100)\cdot x\text{.}`

Now, since the tax should not figure in our calculations, we must subtract it from the car's price. First, let's calculate how much it is, using the percentage formula:

`(10)/(100)\cdot3500=(1)/(10)\cdot3500=(3500)/(10)=350.`

Now, let's subtract it from the car's price:

`3500-350=3150.`

Then, the price of the car is $3150, excluding tax. Finally, to solve the exercise, we only must calculate the 10% of this price, using the percentage formula:

`(10)/(100)\cdot3150=(1)/(10)\cdot3150=(3150)/(10)=315.`Answer

The down payment, excluding tax, for the car is

`\$315.`
