The Lakeside Marina charges a $35 rental fee for a boat in addition to charging $15 per hour. Write the equation that represents the cost, y, of the boat rental in terms of x hours. What is the cost of a rental for 3 hours?

y=35+15x

if it has been rented for 3 hours,

y=35+15(3)

y=35+45

y=80

Step-by-step explanation:

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.
