Find the total amount given the original price and tax rate. Round to the nearest cent if necessary.

Setler79 [48]

Given:

Original price = $15.25

Tax rate = 7%

To find:

The total amount.

Solution:

We know that,

Total amount = Original price + Tax

According to the question,

Total amount = 15.25 + 7% of 15.25

$\text{Total amount}=15.25+\dfrac{7}{100}\times 15.25$

$\text{Total amount}=15.25+1.0675$

$\text{Total amount}=16.3175$

Round to the nearest cent (two decimal places).

$\text{Total amount}\approx 16.32$

Therefore, the total value is $16.32.
