Answer:

$50.75

Step-by-step explanation:

There are 2 half hours in 1 hour. Since he needs the kayak for 3 half hours, you can multiply the $14.50 by 3. You still need to get the extra 15 minutes. Since a half hour is 30 minutes, and 30 divided by 2 is 15, you can divide 14.5 by 2 to get 7.25. 7.25+ (14.5×3)=15.75.
