Questions: Ratios, Proportions, and Percents Word problem on unit rates associated with ratios of whole numbers:... Answer each part. If necessary, round your answers to the nearest hundredth. (a) A color printer prints 17 pages in 5 minutes. How many minutes does it take per page? minutes per page (b) Charmaine bought 18 pounds of rice for 7. How many pounds of rice did she get per dollar? pounds per dollar

Solution Steps

To solve these problems, we need to calculate unit rates. For part (a), we find the time taken to print one page by dividing the total time by the number of pages. For part (b), we determine how many pounds of rice are obtained per dollar by dividing the total pounds by the total cost.

To find the time it takes to print one page, we divide the total time by the number of pages. Given that a printer prints 17 pages in 5 minutes, the time per page is calculated as follows:

\[ \text{Minutes per page} = \frac{5 \text{ minutes}}{17 \text{ pages}} = 0.2941 \text{ minutes per page} \]

To determine how many pounds of rice are obtained per dollar, we divide the total pounds of rice by the total cost in dollars. Charmaine bought 18 pounds of rice for \$7, so the pounds per dollar is:

\[ \text{Pounds per dollar} = \frac{18 \text{ pounds}}{7 \text{ dollars}} = 2.571 \text{ pounds per dollar} \]
