Question

What are two ways to find the total cost of a pair of shoes for $57 with a sales tax of 2%?

Answer 1

Here is one of the ways, first you are going to convert the 2% into a fraction.
2% = 0.02
Next we are going to multiply 0.02 * 57 = 1.14
Now we are going to add 1.14 to 57 to find the total cost with including the tax.
1.14 + 57 = 58.14
= $ 58.14

Answer 2

The total cost is $58.14.

Explanation:

Given : A pair of shoes for $57 with a sales tax of 2%.

To find : What are two ways to find the total cost ?

Solution :

Cost price CP=$57

Sales tax S=2%

One way :

The total cost is given by,

`C=CP+2\%\text{ of } CP`

`C=57+(2)/(100)* 57`

`C=57+1.14`

`C=58.14`

The total cost is $58.14.

Another way :

Using selling price formula,

`SP=(100+S\%)/(100)* CP`

`SP=(100+2)/(100)* 57`

`SP=1.02* 57`

`SP=58.14`

The total cost is $58.14.
