Tax = 8% of x

A/q
x+8%of x = $37.80
⇒x + 8x/100 = 37.80
⇒108x/100 = 37.80
⇒108x = 3780
⇒x = 3780/108 = $35

Actual cost is $35

Answer:

The cost of the Jeans is $35.      

Step-by-step explanation:

Given : Gaetano spent $37.80,including tax, on a pair of jeans.

To find : How much did the jeans cost if there was an 8% sales tax ?

Solution :

Let the cost price of Jeans be 'x'.

Gaetano spent $37.80,including tax, on a pair of jeans.

Sales tax is 8%.

According to question,

$x+8\%\text{ of } x = \ 37.80$

$x+\frac{8}{100}x=37.80$

$\frac{100x+8x}{100}=37.80$

$108x=37.80\times 100$

$108x=3780$

$x=\frac{3780}{108}$

$x=35$

Therefore, The cost of the Jeans is $35.
