An average person has about \( 5 \times 10^{6} \) red blood cells for every cubic millimeter of blood. If there are about \( 4.9 \times 10^{6} \) cubic millimeters of blood in someone's body, how many red blood cells do they have?

Which statement is true? \( \begin{array}{l}-6.9>-1.2 \\ -1.2<6.9 \\ 6.9<1.2 \\ 1.2<-6.9\end{array} \)

Simplify: \(2 \times (3 + 4) + (5 - 2)\)

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? \( \$ \square \)
