x = original price
40% of x = 0.40x = final price
0.40x = 240
x = 240/0.40
x = 600

Answer: $600

.

Since 40% of the item's cost is $240, it means that 10% of the item's cost is 240/4 = 60 dollars.


Hence, the item's full cost is 10 times $60, or $600.    ANSWER

It is how to solve the problem  MENTALLY  for a  5-th grade student
