Question

Sara has some oranges. She sold 40% more than she ate. If she sold 70 oranges, how many did she eat?

Answer 1

The answer would be: she ate 50 oranges.

Here is the reason why (if you needed it):
Let x = the number of oranges that Sara ate.
Thus x + .4x = 1.4x is the number of oranges that Sara sold.
Therefore, 1.4x = 70/1.4 = 50.

Hope this helps :)
