The sum of three consecutive even numbers is 174. what is the smallest of the 3 numbers?

The smallest value is 56.

First even number + second even number + third even number = 174

First even number: x

Second even number: x + 2

Third even number: x + 4

So, (x) + (x+2) + (x+4) = 174

3x + 6 = 174

3x = 168

x = 56

(56 + 58 + 60 = 174)

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).
