I am having trouble figuring out part D, any help would be welcomed!

Mario is setting up a money market savings account with an APR of 3.75% compounded monthly. He also received a $1,200 bonus for working extremely hard to complete a project ahead of schedule.

a. If he opens the money market savings account with his bonus money and then deposits $100 into the account every month, how much money will he have in this account in 5 years?

b. How long will it take for him to accumulate $6,000 for his dream vacation?

c. How much money will he need to deposit every month if he wants enough money to go on his dream vacation in just 3 years?

d. Mario decides that 3 years is too long to wait for his dream vacation. If he ups his monthly contributions to $190, what APR would he need to qualify for so that he can take his dream vacation in just 2 years?

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4

c

step-by-step explanation:

there is vertical asymptote at x = 2 and x = 0

vertical asymptote occurs at the points where the denominator is 0. so we can say that

x = 2 occurs when there is a factor (x-2) in the denominator, and

x = 0 occurs when there is a factor "x" in the denominator

thus, the denominator of the equation would have "x * (x-2)", this is option c only. that's the correct answer.
