Question

Solve the problem by stating the equation you would use to solve and then solving it.

Midtown Antiques collects 5% sales tax on all sales. If total sales including tax are $1568.14, find the portion that is sales tax. Round to the nearest cent

Answer 1

1568.14*0.05=78.40

Answer 2

Divide by 105
Multiply by 100
Subtract this from initial sum ($1568.14)

Answer 3

you want an equation right ?
so lets say the initial cost is (i) and (t) is tax percentage
(t)= .05
(i)= unknown
so the total which is 1568.14 is
(i) + (i * t)= 1568.14

we want to know (i * t) which is the portion that is sales tax but we don't know (i) so lets solve for (i)

we can distribute (i) out

(i)* ( 1 + (1 * t))= 1568.14
(i) * (1 + t ) = 1568.14
so (i) = 1568.14 / (1+t)
(i) = 1568.14/ 1.05

now you know what (i) is

so you can solve (i * t) now. Good Luck
