Question

What is 7%tax of something that costs 2.99

Answer 1

$0.21.

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}=(7)/(100)* \$2.99`

`\text{Amount of the tax}=0.07* \$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 $
