Question

Jordan bought a notebook for $5, 6 pencils for $1 each, and a binder for $9. The sales tax for the whole purchase was $2

Answer 1

1.
$t=$ total
$t=5+6(1)+9$
$t=20$
$20 total

$p=$ sales tax from purchase
$s=$ sales tax percentage
$ts=p\\20s=2 \\ s= \frac{2}{20} \\ s=.1$
$.1(100)=10$
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
$ts=p \\20s=1\\ s= \frac{1}{20} \\ s=.05$
$.05(100)=5$
5% sales tax
