At Kelli's skateboard shop, customers pay an
upfront fee of $12 and then pay $3 per
hour for each hour they use the skateboard.
Write a rental equation for the cost of
renting a skateboard at Kelli's shop.
ht

y = 3x + 12

Step-by-step explanation:

Initial Charge: $12 also known as your asymtope which is the number that it never goes below. It is your y-intercept in this linear equation.

Charge or ROC: $3

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.
