Limei spent 7/10 of her money and saved the rest. She spent $42.

Question

(a) How much money did Limei have at fist?

(b) How much money did she save?

Answer 1

Let's assume Limei had x amount of money at first.

Limei spent 7/10 of her money, so she spent (7/10) * x = $42.
So, x = $42 * (10/7) = $60.

Therefore, Limei had $60 at first.

To find out how much money Limei saved, we need to subtract the amount spent from the initial amount.

Amount saved = Initial amount - Amount spent
= $60 - $42
= $18.

So, Limei saved $18.
