Question

We went on a shopping spree and spent 60% of outmoney. If we spend $120, how much money did wehave originally?

Answer 1

To determine how much money we had in the first place we can use a rule of three:

$\begin{gathered} 120\rightarrow60 \\ x\rightarrow100 \end{gathered}$

Then we have that:

$x=\frac{100\cdot120}{60}=200$

Therefore, you originally has $200
