Question

What is one way to find the total cost of a jacket for $55.80 with a sales tax of 2.7%

Answer 1

55.80 + 55.80 (.027) = 57.3066 or $57.31

Answer 2

`\$57.31`

Explanation:

The total cost would simply be given by multiplying the price by 1.027

1) Divide the tax (2.7%) by 100 and then, add 1 unit

`(2.7)/(100)=0.027+1\Rightarrow 1.027`

2) Multiply by the price ($55.80):

`1.027*\$55.8\approx \$57.31`
