Answer:
$16.05
Explanation:
We must ADD 7% sales tax to the price of the football. ($15.00)
But what is 7% of $15.00?
First we must convert 7% to a decimal.
To do that we move the existing invisible decimal two places to the left.
So in 7% the invisible decimal is here
7.0
_^
If we move it two places to the left then we have
. 7
^__
Always fill in the space(s) with 0.
.07 Is the same as 7%
So what is 7% of $15.00?
Well we have to multiply the price of the football by the percentage of sales tax.
15 × .07 = 1.05
Same as: $15.00 × 7% = $1.05
$1.05 is 7% of $15.00
Last, to find the total price including sales tax, we must ADD the sales tax to the price of the football
$15.00 + $1.05 = $16.05
Hope this helps!
