Question

Erin caught 8

more fish than Juan caught.

Is this situation modeled by an expression or equation? How do you know?

Answer 1

I would say it is modeled by an equation because it is saying that Erin is equal to Juan's number of fish plus eight. ( E= J+ 8) or (J= E-8)

Answer 2

yes

Explanation:

This situation can be modeled as an equation because it is a relationship between two quantities. I mean we can know a new quantity, knowing how it relates to another quantity already known. in this case we can know the number of fish caught by ernin, by knowing how many fish Juan caught or vice versa.

E(J)= J+8 where j is the number of fish caught by Juan and E is the number of fish caught by ernin
