Write a real world problem that describes a proportional relationship.

Question

I need help please I need this done soon. Thank you.

Answer 1

A proportional relationship includes two or more quantities which change if the other changes.  A real-world problem could be something as common as a trip to the grocery store.

 

If one candy bar costs $2, how many candy bars could be bought with $8?

 

This can be expressed as the linear function y = 2x. 

 

A person could confidently say "four candy bars" because the price of candy is explicitly dependent on the number of bars purchased.
