Rosa bought a new hat when she was on vacation. the following formula describes the percent sales tax rosa paid. b = t - c / c where t= total price rosa paid for the hat c= total cost of the hat b= sales tax (percent) rewrite the formula to determine the total cost rosa paid for the hat.

The given formula is

Where B is the sales tax.

T is the total amount she paid for hat, and

C is the total cost of the hat .

In this question , we need to solve for T

We start with getting rid of the denominator C, by doing cross multiplication, that is

Now we need to get rid of the C that is in the right side and for that we add C .

It can also be written as

C is the common factor in the right side .

And that'sthe required answer .

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.
