Danny mixed \( 58 \ell \) of water with \( 33 \ell \) of lemon juice to make lemonade for the school carnival. \( 42 \ell \) of lemonade were sold. How much lemonade was left?

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. 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? \( \$ 15 \) c) How many lawns must Jimmy mow before he begins making a profit? (Round to the nearest integer as needed.)
