Sadie runs a farm stand that sells blueberries and peaches. Each pound of blueberries sells for $3.25 and each pound of peaches sells for $3. Sadie sold 3 times as many pounds of peaches as pounds of blueberries and she made $171.50 altogether. Determine the number of pounds of blueberries sold and the number of pounds of peaches sold.

There were 14 pounds of blueberries sold and 42 pounds of peaches sold.

Step-by-step explanation:

Since Sadie sold 3 times as many pounds of peaches as pounds of blueberries, she sold more pounds of peaches, so if we multiply 3 by the number of pounds of blueberries sold, we will get the number of pounds of peaches sold, meaning pp equals 3b.

There were 14 pounds of blueberries sold and 42 pounds of peaches sold.
