A boy spent one-half of his money for a book and one-third of his money for a pen. The remaining $2.25 he saved. How much money

Tema [17]

Let his original money is x

So, $\frac{x}{2}$ + $\frac{x}{3}$ + 2.25 = x
or, $\frac{3x+2x+(6*2.25)}{6} = x$
or, 5x + 13.5 = 6x
or, x = 13.5

So, he had $13.5 originaly.

Thanks!
