Answer each part. If necessary, round your answers to the nearest hundredth \( \begin{array}{l}\text { (a) It takes } 19 \text { pounds of seed to completely plant a } 3 \text {-acre field. } \\ \text { How many pounds of seed are needed per acre? } \\ \text { (b) At Garcia's Bike Rentals, it costs } \$ 43 \text { to rent a bike for } 8 \text { hours. } \\ \text { How many hours of bike use does a customer get per dollar? } \\ \square \text { hours per dollar }\end{array} \)

To tackle these problems, let's break them down one by one. (a) To find out how many pounds of seed are needed per acre, we simply divide the total pounds of seed by the number of acres. \[ \text{Pounds of seed per acre} = \frac{19 \text{ pounds}}{3 \text{ acres}} \approx 6.33 \text{ pounds per acre} \] So, you need approximately 6.33 pounds of seed per acre. (b) For the bike rental cost, we need to determine how many hours a customer can rent a bike per dollar. We can do this by dividing the total rental hours by the cost of the rental. \[ \text{Hours per dollar} = \frac{8 \text{ hours}}{43 \text{ dollars}} \approx 0.186 \text{ hours per dollar} \] Therefore, a customer gets about 0.19 hours of bike use per dollar spent.
