Question

Sara sells dolls at her doll store. If she has a doll that she sells for $15.55, what would be the total cost of the doll if the sales tax were 6% of the sale price?

Answer 1

$16.48

Explanation:

If 6% is sales tax, that means that the total cost of the doll is 106% of the original cost. (basically 100% is the originall doll, and you add 6% of the tax). If you convert 106% from percentage form to decimal form (which you do by dividing by 100), 106% is the same as 1.06 times the original cost of the doll.

Thus you do 1.06 x 15.55 = 16.483 which rounds down to $16.48
