Will's Watersports made a total of $780 from renting 12 jet skis and 9 kayaks. Family Fun Rentals made a total of $570 from renting 7 jet skis and 11 kayaks. What is the cost of each type of rental?

I think its

Jet Skis:$42

Kayaks:$70

Step-by-step explanation:

$780 = 12 jet skis and 9 kayaks

$570 = 7 jet skis and 11 kayaks

12x+9y+780=570+7x+11y

x=0

11-9=780-570

3=210

210/-3=70

y=0

12-7=780-570

5=210

210/5 = $42

its c or d   take a lucky guess my dude
