Mike and Krista rent a jet ski while on vacation. The rental cost is represented by the function c (h) = 50+20h, where the number of hours of use and c (h) is the total cost for h hours of use. How much does a jet ski cost if they use it for 4 hours

130

Step-by-step explanation:

Given the equation of the relation as c (h) = 50 + 20 h where c (h) is the total cost for h hours and h is the number of hours of use, then to find the cost of jet ski if 4 hours were used will be;

c (h) = 50 + 20 h

c (4) = 50 + 20*4

c (4) = 50 + 80
