Question

Betty has a cow . The cow produces 5 liters of milk each day . If his diet improved , the cow will produce 200% more milk . How much milk will he produce in a day , if that were to happen ? This is not a proportion problem.

Answer 1

The cow produces 5 liters a day. 
You want to find how much it will produce a day if the cow produces 200% more milk. So, you use the equation p*(1+x/100)
5×(1+200/100)=15
