Henry drinks 15 bottles of kombucha every month.  Each bottle costs $3.00 and is eligible for a cash refund of $0.10 per bottle when he takes it to a recycling center.  After 1 year, how many bottles of kombucha will he be able to buy after he receives his cash refund?
He drinks 15 bottles every month and there are 12 months in 1 year so that's 15*12 = <T>multiply(15, 12)=180 bottles
He earns $0.10 on every bottle that he recycles so that's .10*180 = $<T>multiply(0.1, 180)=18.0
He has $18.00 and each bottle costs $3.00 so he can buy 18/3 = <T>divide(18, 3)=6.0 bottles
