Question

1. A limited-edition soccer ball costs $30, and the
sales tax is 6%. What is the total cost?

Answer 1

$31.80

Explanation:

First, find how much the sales tax is

$30 × 6%

Convert the percentage into a decimal

30 × 0.06

1.8

$1.80

Add the sales tax to the original cost

$30 + $1.80

$31.80

Answer 2

$31.80

Explanation:

The ball will cost 100% of its price plus 6% of its price for a total of 106%.

To use percentages as a factor and multiply, they must be divide by 100, making the multiplication factor version of 106% 1.06.

Multiply the cost of the ball by your multiplication factor:

30 x 1.06 = 31.8

Money is written to two decimal places, making your answer $31.80
