Nicole sells candy bars at a tailgate party to raise money for her school sports club. She bought them at 4 for $1, and sold them at 2 for $1. How many candy bars must be sold in order to raise $5?
if she bought 4 for 1$ and sells 2 for 1$ that means she sells 4 for 2$ so every 4 she buys she makes 1$ so in order to make 5$ their must be 5 x 4bars so 20bars must be bought
