Question

a trader bought some oranges at 75 cents each. she finds that 6 of them are spoilt. she sells the rest at 1 dollr each and makes a profit of 31.50 dollars. how many oranges did she buy ?

Answer 1

Let n be the number of oranges bought @ $0.75 each. The profit, $31.50, is equal to the sales amount minus the cost. Solve the following for n:

1.00 (n - 6) - 0.75 n = 31.50
n = 150 oranges

Checking the answer:
144*1 - 150*0.75 = 31.5
