Mp 2.3, 7 molina noticed that when she
had three consecutive integers, such as 3, 4, 5,
that (3)(5) = 15 and 4= 16. and, again, with
6,7,8, that (
68) = 48, while 72 = 49. after
working with both positive and negative
integers, molina offered the following con-
jecture: given any three consecutive integers,
starting with x, the product of the first and
the third is one less than the square of the
second. clearly identify your own variables
and show that, algebraically, she's right.

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).
