A bacteria has an initial population of 500 and is doubling every hour. The bacteria reaches a population of 16,000 bacteria.
Which equation could represent the situation described and how long does it take for the bacteria to reach 16,000?

what do you need me to answer?

step-by-step explanation:

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).

answer: 100
