6.03] what is the value of the x variable in the solution to the following system of equations?
3x + 2y = 8
2x + 3y = 2
4
−2
x can be any number as there are infinitely many solutions to this system
there is no x value as there is no solution to this system

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).

step-by-step explanation:

for volume, add base x height x width
