Answer

Explanation:

Step1: Calculate the printing rate of Copier A

$$R_A = \frac{350 \text{ pages}}{7 \text{ minutes}} = 50 \text{ pages/minute}$$

Step2: Calculate the printing rate of Copier B

$$R_B = \frac{210 \text{ pages}}{3 \text{ minutes}} = 70 \text{ pages/minute}$$

Step3: Find the difference between the two rates

$$\text{Difference} = R_B - R_A = 70 - 50 = 20 \text{ pages/minute}$$
