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? Let's be accurate as possible.
He drinks 15 bottles every month and there are 12 months in 1 year so that's 15 * 12 = 180 bottles. He earns $0.10 on every bottle that he recycles so that's .10 * 180 = $18.00. He has $18.00 and each bottle costs $3.00 so he can buy 18 / 3 = 6 bottles.
The answer: 6.
