Final Answer: The price of one carton of strawberries is \(\boxed{4}\) dollars and the price of one carton of raspberries is \(\boxed{5}\) dollars.

Steps

Step 1 :Let the price of one carton of strawberries be s and the price of one carton of raspberries be r. We have the following system of linear equations:

Step 2 :\(3s + 2r = 22\) (Rahim's purchase)

Step 3 :\(4s + 5r = 41\) (Paul's purchase)

Step 4 :Use the elimination method to solve the system of equations. Multiply the first equation by 2 to make the coefficients of r the same in both equations:

Step 5 :\(6s + 4r = 44\)

Step 6 :\(4s + 5r = 41\)

Step 7 :Subtract the first equation from the second equation to eliminate r:

Step 8 :\(-2s + r = -3\)

Step 9 :Solve for r:

Step 10 :\(r = 2s - 3\)

Step 11 :Substitute this expression for r back into the first equation:

Step 12 :\(3s + 2(2s - 3) = 22\)

Step 13 :Solve for s:

Step 14 :\(3s + 4s - 6 = 22\)

Step 15 :\(7s = 28\)

Step 16 :\(s = 4\)

Step 17 :Find the value of r:

Step 18 :\(r = 2(4) - 3\)

Step 19 :\(r = 8 - 3\)

Step 20 :\(r = 5\)

Step 21 :Final Answer: The price of one carton of strawberries is \(\boxed{4}\) dollars and the price of one carton of raspberries is \(\boxed{5}\) dollars.
