Question

On Monday, Hakim stocked up on bottled water for the trip. On Tuesday, he purchased five more bottles to add to his collection. On Wednesday, half of his entire collection remained and he only had 7 left. How many did he have on Monday?​

Answer 1

9

Explanation:

You can solve this easily by working backwards. It says on wednesday that half of the water bottles were remaining, which means there were 14 before. 7*2=14. It says he purchased 5 more bottles on tuesday, so you just subtract 5 from 14 and you get 9. To double check, 9+5=14 14/2=7.
