First, we know that Marco and his dad went strawberry picking and together they collected strawberries that weighed 36 pounds. 

Next, we know that on the way back Marco's dad lost 8 pounds of strawberries. 

That means that Marco's strawberries now weigh 12 pounds. 

Now we just have to solve for how much his dad's strawberries weigh now. 

We can do this by setting up an equation. 

We know that the total weight of the strawberries is 36 pounds. 

We also know that Marco's strawberries weigh 12 pounds. 

That means that we can say that 36 pounds is equal to 12 pounds plus the weight of his dad's strawberries. 

We can solve this equation for the weight of his dad's strawberries. 

36 pounds = 12 pounds + the weight of his dad's strawberries 

24 pounds = the weight of his dad's strawberries 

That means that his dad's strawberries now weigh 24 pounds.
