Question

What is 7%tax of something that costs 2.99

Answer 1

Answer:

$0.21.

Step-by-step explanation:

We have been given that the cost of an item is $2.99. We are asked to find the amount of 7% tax for the given item.

To find the amount of tax, we need to figure out 7% of $2.99.

$\text{Amount of the tax}=\frac{7}{100}\times \ 2.99$

$\text{Amount of the tax}=0.07\times \ 2.99$

$\text{Amount of the tax}=\ 0.2093$

$\text{Amount of the tax}\approx \ 0.21$

Therefore, the tax of the item that costs $2.99 would be approximately $0.21.

Answer 2

 For this case we can make the following rule of three:
 2.99 ----------> 100%
 x --------------> 7%
 From here, we clear the value of x.
 We have then:
 $x = (7/100) * (2.99)$
 Rewriting the expression we have:
 $x = (0.07) * (2.99) x = 0.2093$
 Answer:
 The sales taxes are:
 x = 0.2093 $
