Lizzy: Jack collects all his neighbors' recycling and sorts out the cans and bottles to return for the deposit. He gets 10 cents per bottle and 5 cents per can. If he recycled 80 bottles and made $15, how many cans did he recycle?.
Me: Hmmm, let me think. I think this is the detailed solution:
First find the total amount Jack earned from the bottles: $0.10 / bottle * 80 bottles = $8.00. Then subtract that amount from his total earnings to find the amount he earned from cans: $15.00 - $8.00 = $7.00. Then divide his total earnings from cans by his earnings per can to find the number of cans he recycled: $7.00 / $0.05 / can = 140 cans. Final answer: 140.
