Leo buys 5 DVDs for 60$. At this rate, how much would he pay for 3 DVDs?
60 divided by 5,
is 12.
In which case,
12 times 3...
Is 36$.
So Leo would pay 36$ for 3 DVDs at the rate of 12$ for each DVD
\(\frac{\$60}{5}=\frac{x}{3}\ \ \ \ \ \ |cross\ multiply\\\\5x=3\times\$60\\\\5x=\$180\ \ \ \ \ \ |divide\ both\ sides\ by\ 5\\\\\boxed{x=\$36}\leftarrow answer\)
