A college has a financial aid formula that applies to applicants whose family's income is below a certain threshold. The financial aid can be determined by the function
f(x) = 20000 + 3000c, where x is the number of siblings (including half siblings
and step siblings) that the applicant has living in their household. Find and interpret
the given function values and determine an appropriate domain for the function.

can i see the following ?

step-by-step explanation:

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)

3 qrs + 3/2 xy hope this : /

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).
