Afootball is originally priced at $15. in this state, the sales tax rate is 7%. what
was the total price of the football?

15 * 107%= 16.05

Step-by-step explanation:

$16.05

Step-by-step 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!

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
