Three of the four golfers 1 l of water. the fourth golfer drinks 1.5 l of water. how many milliliters of water did the group drink in all?

me i can't frigure this out.

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).

could u provide us some answer choices or hmm idk maybe a table for us to anser with ? ?
