A shop gave a discount of $6 for every $40 spent. Mrs Ravi bought a dress and paid $117. What was the price of the dress before the discount?
+37159 x = origianl price
x - 6 * x/40 = 117
34/40 x = 117
x=117*40/34 = 137.65 dollars Assuming prorated discounts ( i.e. 6 discount for 40 3 discount for 20 etc)
If no prorated discount
x - 18 = 117
x = 135 dollars
