Answer to Problem 50PPS
Total Cost rent for two jet-skis and two life jackets for 8 hours = $1210
Explanation of Solution
Given information:
Charge for each jet-ski per hour =
Charge for life jacket =
Equation of given situation is
Total rent of Cost for each jet-ski
We need to find total rent for two jet skis and two life jackets for 8 hours
Substitute
We get
Therefore
Total rent of one jet ski for 8 hours =
Multiplying with 2 on both sides
We get
Therefore
Total Cost rent for two jet-skis and two life jackets for 8 hours = $1210
