I'm using double number lines. Martin bought 3 DVDs for $15.00 on Black Friday. At this price, how much would 8 DVDs cost?

bagirrra123 [75]

First of all, I find it easiest to write n equation.

3 / 15 x 8 =

Now that we have an equation, we can figure out a solution.

3 / 15 = 5
5 x 8 = 40

So 8 DVD's would cost $40.00.
