Word problem on unit rates associated with ratios of whole numbers:... Answer each part. If necessary, round your answers to the nearest hundredth. \( \begin{array}{l}\text { (a) A color printer prints } 10 \text { pages in } 4 \text { minutes. } \\ \text { How many pages does it print per minute? } \\ \square \text { pages per minute }\end{array} \) \( \begin{array}{l}\text { (b) Raina bought } 18 \text { pounds of flour for } \$ 10 \text {. } \\ \text { How many dollars did she pay per pound of flour? } \\ \square \text { dound }\end{array} \)

First, let’s tackle part (a)! To find out how many pages the printer prints per minute, you simply divide the total pages by the total minutes: \[ \text{Pages per minute} = \frac{10 \text{ pages}}{4 \text{ minutes}} = 2.5 \text{ pages per minute.} \] Now onto part (b)! To find out how much Raina paid per pound of flour, divide the total cost by the total weight: \[ \text{Dollars per pound} = \frac{10 \text{ dollars}}{18 \text{ pounds}} \approx 0.56 \text{ dollars per pound.} \] So, to summarize: (a) 2.5 pages per minute (b) Approximately $0.56 per pound.
