The FFA has $2400 in a fund to raise money for a new tractor. They are selling trees and have determined that the number of trees they can buy to sell depends on the price of the tree p, according to the function n(p) = 2400. Also, after allowing for profit, the number of trees that customers will purchase depends on the price which the group purchased the trees with function cp) = 300 - 6p. For what price per tree will the number of trees that can be equal the number of trees that will be sold?

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.

step-by-step explanation:

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
