17 - $49 - $19 = 30
$30/ $5 per hour = 6 hours
Darryl rented the bike for 6 hours
18 - If there are 22 posters left, and half of them burned, so that means that originally there were double of 22 which is 44.
So he had 44 originally but bought 6 more and we have to double the six so that's 44 + 12 = 56
Adam had 56 posters to start with
Your answer is: Darryl- 6 hours; Adam- 56 posters
Have an amazing day!
