Marco and his dad went strawberry picking. Marco's strawberries weighed 10 pounds. If together their strawberries weighed 26 pounds. How much more did his dad's strawberries weigh than his?
. 

Marco's strawberries weigh 10 pounds. 

We are told that together, Marco and his dad's strawberries weigh 26 pounds. 

We want to know how much more did his dad's strawberries weigh than his. 

We can set up an equation to solve this. 

Let's use the variable d to represent his dad's strawberries. 

We know that Marco's strawberries weigh 10 pounds, so we can write: 

d + 10 = 26 

We can solve this equation for d. 

d + 10 = 26 
d + 10 - 10 = 26 - 10 
d = 16 

We know that his dad's strawberries weigh 16 pounds.
