Express the tax as a percentage.( The second one)

Answer 1

1.

`t=` total

`t=5+6(1)+9`

`t=20`
$20 total


`p=` sales tax from purchase

`s=` sales tax percentage

`ts=p\\20s=2 \\ s= (2)/(20) \\ s=.1`

`.1(100)=10`
10% sales tax

2.

`t=` total

`t=6+2(3.5)+2(3.5)`

`t=6+7+7`

`t=20`
$20 total


`p=` sales tax from purchase

`s=` sales tax percentage

`ts=p \\20s=1\\ s= (1)/(20) \\ s=.05`

`.05(100)=5`
5% sales tax
