John and Zeke work at Star bucks making espresso drinks. The store has two espre sso mac hines, an old one and a new one. The newer espresso machine is faster, but you can only pull one shot at a time on it. Zeke is faster than John on both machines. The foll owing are the time (in minutes) it takes each worker on each m achine to pull "s" shots. Assume time is the only relev ant cost.

Zeke

(_new) = 2²

(_old) = 3 + 3²

John

(_new) = 2 + 3²

(_old) = 5 + 4²

Suppose you have Zeke working on the new machine and John working on the old machine. They have to pull 30 shots total each shift. How many should Zoe do and how many should JP do?
