<human>:  Frank picked 36 apples. Susan picked 3 times as many apples as Frank. If Susan gave out half of her apples, and Frank sold a third of his, how many in total do they have left?
<bot>: How many apples did Susan pick? ** Susan picked 3 times as much as 36 which is 3*36 = <<3*36=108>>108 apples
How many apples did Susan give out? ** She gave out half which is 108*(1/2) = <<108*(1/2)=54>>54 apples
How many apples does Susan have left? ** She now has 108-54 = <<108-54=54>>54 apples
How many apples did Frank sell? ** Frank sold a third of 36 which is 36*(1/3) = <<36*(1/3)=12>>12 apples
How many apples does Frank have left? ** Frank now has 36-12 = <<36-12=24>>24 apples
How many apples do Frank and Susan have left? ** Altogether they now have 54+24 = <<54+24=78>>78 apples
