Factorizations of 28 :

A \( 24 / 7 \) covered parking lot charges \( \$ 8 \) to enter and \( \$ 4.25 \) per hour to stay. What is the initial value? What is the rate of change? How much does it cost to park for 12 hours?

\( \int x ^ { 2 } \sqrt { x ^ { 3 } + 1 } d x , \quad u = x ^ { 3 } + 1 \)

\( \frac { 2600 } { } \)

Jimmy decides to mow lawns to earn money. The initial cost of his electric lawnmower is \( \$ 350 \). Electricity and maintenance costs are \( \$ 6 \) per lawn. Complete parts (a) through (c) a) Formulate a function \( C(x) \) for the total cost of mowing \( x \) lawns. \( C(x)=350+6 x \) b) Jimmy determines that the total-profit function for the lawn mowing business is given by \( P(x)=9 x-350 \). Find a function for the total revenue from mowing \( x \) lawns. \( R(x)=15 x \) How much does Jimmy charge per lawn? \( \$ \square \)
