Question

Rylie wants to purchase a homecoming dress.

Rylie has not decided on a dress so the cost (C) of the dress
is unknown. Rylie does know that the sales tax she will have
to pay is 8% of the total cost. Which two expressions could
be used to calculate Rylie's total cost after tax?

(1) 0.92c
(2) c+0.08c
(3) c-0.08c
(4) 1.08c

Answer 1

2 and 4

Explanation:

8% = 0.08

Tax is added to the cost (c) of the dress so c + 0.08c would be correct. That would come out to 1.08c so that would also be correct.
