cost = 100.
gross sales tax = 7% (i think that's what this is).

p = (r-c)/c

p = price
r = revenue or sale price
c = cost.

storekeeper wants a profit of 37%.

.37 = (r-100) / 100

multiply both sides of this equation by 100 to get:

37 = r - 100

add 100 to both sides of this equation to get:

137 = r

that's the sale price.

7% GST on that would be equal to .07 * 137 = 9.59.

the item must be price at 137 plus 9.59 tax = 146.59.

price includes tax.

item is sold for 146.59.

vendor pays sales tax to government and keeps the rest for himself.

vendor keeps 137.

profit is 137 - 100 = 37.

percent profit is 37/100 = .37 = 37%.

The statement of the problem is misleading. The sales tax has nothing to do with the price she needs to set to make a 37% profit.

If the cost was $100, the profit needs to be 37% of $100, which is $37; so the sale price must be $137.

The cost to the customer will be $137 plus 7% sales tax, or 1.07($137) = 146.59; but that figure has anything to do with the question that was asked.
