Steve buys a new coat from don’s clothing store. don buys coats from marys

Your answer would be: B. Interdependence

This is because Steve buys a new coat from Don’s clothing store. Don’s clothing store is a retail shop. Steve is a customer. Don buys the coat from Mary, therefore Mary is the manufacturer who prepared the coat. Mary buys the material from the Sean’s mill. The raw material provided to Mary is from Sean’s mill. If the workers in the Sean’s mill get raises, there is an increase in direct cost for Sean’s mill and the cost of materials will increase. Sean will sell the same material at a higher price to its customers. Which is why when Mary buys from Sean’s at a higher price, it will sell its end product coat to Don at a higher price. Thus, for Steve, Mary and Don it is an interdependence of each other.

hope this helps!

Molarity is moles of solute over liters of solution. idk if that is what you are talking about, but you can convert moles of solute to grams of solute using dimensional analyzes by using molar mass found on the periodic table.
