STEP 1:
find the sales tax (decimal form)
x= sales tax
Cost + (Cost * Sales Tax)= Total
plug in known numbers
$9.40 + ($9.40 * x)= $9.87
9.40 + 9.40x= 9.87
subtract 9.40 from both sides
9.40x= 0.47
divide both sides by 9.40
x= 0.47/9.40
x= 0.05 sales tax decimal form
STEP 2:
find sales tax percentage
= 0.05 * 100
or move decimal to the right two decimal places
= 5% sales tax percent form
ANSWER: The sales tax is 5% (or 0.05 in decimal form)

Answer:
6,489
Step-by-step explanation:
first you would multiply 7 and 9, which would be 63
7 x 9 = 63
then you would multiply 63 by 103 since they are being multiplied
63 x 103 = 6,489
So 10% of 12=1.2 divided by
2 to get 5% which is 0.6 so because it’s increasing the amount you do $12 + 0.6 =
$12.6 if you pay online
