- 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 \[\nc=12+3 h \quad c=12+3(5)=12+36=48 \text{ }\$ \]

Kelli's skateboard rental shop follows a straightforward pricing model that helps customers easily calculate their total cost. The base fee is \( \$12 \), allowing customers to skate for an hour or even longer! The equation \( c = 12 + 3h \) signifies that for every hour \( h \) spent riding, an additional \( \$3 \) is added on top of the initial fee. So, for five hours, the math checks out: \( c = 12 + 3(5) = \$48 \). If you're planning to use a skateboard for an extended period, you might want to consider the total cost beforehand to avoid surprise charges. A common mistake is underestimating the total hours of use! Remember, every hour can add up quickly, so it's wise to plan your time in advance and maybe even time your last runs effectively to maximize fun without breaking the bank.
