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?
Kim got 2 candy bars a week for 16 weeks so she got 2*16 = <T>multiply(2, 16)=32 candy bars
She would only eat 1 candy bar every 4 weeks so in 16 weeks she only ate 16/4 = <T>divide(16, 4)=4.0 candy bars
She saved 32 candy bars and only ate 4 so she still has 32-4 = <T>subtract(32, 4)=28 candy bars
