To find the cost per hour in general, we can calculate the rates paid by David and Jennifer per hour:
David paid $18.5 for 3 hours, so his rate per hour is $18.5 / 3 = $6.17 per hour.
Jennifer paid $14.0 for 2 hours, so her rate per hour is $14.0 / 2 = $7.00 per hour.
To find the initial rental cost in general, we can calculate the difference between the total amount paid and the cost of skating for the given hours:
For David:
Initial rental cost = $18.5 - ($6.17 * 3) = $18.5 - $18.51 = $0.01
For Jennifer:
Initial rental cost = $14.0 - ($7.00 * 2) = $14.00 - $14.00 = $0.00
Therefore, the cost per hour in general is $6.17 and the initial rental cost in general is $0.01.
At the skating rink. David paid 18.5 and skated for 3 hours while Jennifer skated for 2 hours and paid $ 14.0 Both of the prices include the price of renting skates
