Solution :-
Let the cost of jeans before the sales tax be $. x
Price including sales tax = $ 37.8 (Given)
According to the question.
⇒ x + (x*8)/100 = 37.8
⇒ x/1 + 2x/25 = 37.8
Taking L.C.M. of the denominators and solving it.
x/1 + 2x/25 = 37.8
⇒ (25x + 2x)/25 = 37.8
⇒ 27x/25 = 37.8
⇒ 27x = (25*37.8)
⇒ 27x = 945
⇒ x = 945/27
⇒ x = 35
So, the cost of jeans before tax was $ 35
