the rental fee to rent jet skis varies directly as the number of hours that you rent them. fun vacation rentals rents jet skis to tourists. they charge $140 for 4 hours . suppose you rent a jet ski for only 3 hours . write and solve a direct variation equation to determine your rental fee ?



Answer :

140/4 = 35 
$35 per hour
so 35 x 3 = 105 

=$105
140 for 4 hours means they must charge 35 dolars for one hour. that means for 3 hours, it would be 105.
