Ruby invested $850 in an account paying an interest rate of 2 7/8% compounded quarterly. Logan invested $850 in an account paying an interest rate of 2 3/8%
compounded monthly. After 17 years, how much more money would Ruby have in
her account than Logan, to the nearest dollar?

answer: a.   one is a factor of every whole number since every number is divisible by itself.

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.

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).
