Kim's dad would buy her 2 candy bars a week. She would eat 1 candy bar every 4 weeks, saving the rest. After 16 weeks, how many candy bars did Kim have saved? Let's be accurate as possible.
Kim got 2 candy bars a week for 16 weeks so she got 2 * 16 = 32 candy bars. She would only eat 1 candy bar every 4 weeks so in 16 weeks she only ate 16 / 4 = 4 candy bars. She saved 32 candy bars and only ate 4 so she still has 32 - 4 = 28 candy bars.
The answer: 28.
