If 30 men do a work in 40 days, then in how many days will 15 men complete same work.

Wait is this a trick question?? Because if 15 men are doing the same work that 40 men did the work would already be done right?

I love riddles.

Have a great day.

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).

i think it is c hope that
