<human>:  Oranges have 80 calories and cost $1.20 each. If Timmy has $10 and needs to make sure he gets 400 calories, how much money will he have left after he buys the oranges he needs?
<bot>: How many oranges does Timmy need? ** He needs to buy 5 oranges because 400 / 80 = <<400/80=5>>5
How much will the oranges cost? ** These will cost $6 because 5 x 1.2 = <<5*1.2=6>>6
How much money will Timmy have left after buying the oranges? ** He will have $4 left because 10 - 6 = <<10-6=4>>4
