Suppose a local vendor charges $2 per hot dog and that the number of hot dogs sold per hour is given by

x (t) = - 4t^2 + 20t + 64,

where t is the number of hours since 10 AM,

0 ≤ t ≤ 4.

Find an expression for the revenue per hour R as a function of x?

A bicyclist is training for a race. On the first day of training, she rides 12 miles. She increases the distance she rides by 3 miles each day. Write an explicit formula to represent this scenario.
