Question

There is a sales tax of $5 on an item that costs $52 before tax. At the same tax rate, what is the sales tax on an item costing $130 before tax?

Answer 1

$5/$52 = $X/$130
multiply both sides of the equation by $130
$130*$5 / $52 =$X
$130*$5 / $52 = $12.50 tax

Answer 2

$5 on $52 then on $130 tax will be
=($5)(130/52) = $12.50

Answer 3

first find the tax rate

5/52 = 9.61 %

now apply it to the new item:

130 x 5/52 = $12.50 in tax

Answer 4

first find the tax rate

5/52 = 9.61 %

now apply it to the new item:

130 x 5/52 = $12.50 in tax

Answer 5

tax = rate x price
$5 = rate x $52 ==> therefore, tax = 0.0961 or 9.61%

the sales tax, therefore, on the $130 item is
0.0961 * 130 = $12.50

Answer 6

so the total cost is $57

I = P(1 + r)
57 = 52 = ( 1 + r)
57/52 = 1 + r
r = 57/52 - 1
r = 5/52

so the tax rate is 5/52

130 + 5/52(130)
= $142.5

142.5 - 130 = $12.5

Answer 7

130/52 x 5 = $12.50.

Answer 8

so you need to find what percentage of the $52 is $5
Its always easier to think of an example like this

sales tax = $10
item before tax = $100

percentage increase = 10/100 = 10%

so for your question you do the same thing

Sales tax = $5
Item before tax = $52

percentage increase = 5/52 = 9.6 % (rounded to 1 decimal place)

so then just work out 9.6% of $130
=$12.48

(I don't have my calculator today so please check it on yours)

Answer 9

$12.50

5 * 130 = 52 *x

Answer 10

i come to 12.5$
i've set it up like this: 5 on 52 = x on 130. the result is 12.50$.
hope it helps
