What I did was I know that if I were to Start out by buying 10 bundles of 4 that would be 40 boxes so far which $5.00*10= $50.00. then I would buy two more bundles of 4 And that would be 10 more $ (5*2=10) so I would be at $60.00 so far but now I have to buy two more boxes of popcorn to be at 50 boxes so I would only have to spend half the original amount since 2 is half of 4 and 5/2=2.5 so that’s where the $2.50 comes in totaling $62.50.
