: So the answer is {{{x=100}}} This means that Mary had $100 originally.

Let x = original amount of money Since we know that because "Mary spent 2/5 of her money", she'll have {{{3/5}}} of her money left (since {{{1-2/5=3/5}}}). So she has {{{(3/5)x}}} dollars left. Now we also know that she has "$60 left", so this means that {{{(3/5)x=60}}} {{{(3/5)x=60}}} Start with the given equation. {{{3x=5(60)}}} Multiply both sides by 5. {{{3x=300}}} Multiply. {{{x=(300)/(3)}}} Divide both sides by {{{3}}} to isolate {{{x}}}. {{{x=100}}} Reduce. ----------------------------------------------------------------------
