Marco and his dad went strawberry picking. Marco's strawberries weighed 15 pounds. If together their strawberries weighed 37 pounds. How much did his dad's strawberries weigh?
. 

Step 1: Marco's strawberries weigh 15 pounds. 
Step 2: Together, Marco and his dad's strawberries weigh 37 pounds. 
Step 3: We want to know how much his dad's strawberries weigh. 

To solve this problem, we can use algebra. We know that Marco's strawberries weigh 15 pounds, and we know that together, Marco and his dad's strawberries weigh 37 pounds. We want to solve for his dad's strawberries, so we'll set up the equation: 

15 + x = 37 

To solve for x, we'll subtract 15 from each side of the equation. 

15 + x = 37 
-15 -15 
0 + x = 22 

Now we can see that his dad's strawberries weigh 22 pounds.
