There are two exam rooms X and Y. We are told the following: If 10 students are sent from X to Y, the number of students in each room becomes the same.

On the other hand, if 20 students are sent from Y to X, the number of students in X becomes double the number of students in Y.

Find the (original) number of students in each room:

The function c(n) below relates the number of bushels of apples picked at a pick-your-own orchard to the final cost for the apples. it takes as input the number of bushels of apples picked after paying an entry fee to an orchard and returns as output and returns as output the cost of the apples (in dollars)c(n) = 15n + 30which equation below represents the inverse function n(c), which takes the cost of the apples as input and returns the number of bushels picked as output
