Joe puts his trading card collection in a folder Each page of the folder holds 9 cards. He has 1,356 trading cards Complete the statement to tell the number of pages Joe completely fills and the number of trading cards he has left over

If he has 1,356 cards and each page he has holds 9 cards, we don't know how many pages he has, so that will be x

1,356/9x 1,356 (# of cards) divided by 9 (cards each page holds) times x (# of pages)

Divide 9x by 9 to get x by itself 9x/9=x

Then, what you do to one side you must do to another so divide 1,356 by 9 1,356/9=150.667

He needs 150 pages and has .667 left over.

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).

sweetheart, there isn't a cube below.
