ariana is going to invest in an account paying an interest rate of 1.9% compounded monthly. how much would ariana need to invest
vitfil [10]

9514 1404 393

Answer:

  $84,330

Step-by-step explanation:

The compound interest formula gives the value of an investment.

  A = P(1 +r/n)^(nt)

where principal P is invested at annual rate r compounded n times per year for t years. Using your given values, we can solve for P.

  110,000 = P(1 +0.019/12)^(12·14)

  P = 110,000/(1 +0.019/12)^(12·14) ≈ 110,000/1.00158333...^168

  P ≈ 110,000/1.30446

  P ≈ 84326.04 ≈ 84,330 . . . . dollars

Someone drove 20 miles in 24 minutes at this rate how many miles did they drive in 6 minutes
nikklg [1K]
Distance = rate * time (I will abbreviate as d = rt)
d = rt, so r = d/t 
r = 20mi/24min
= 0.833333 mi/min.

d = rt again for the new time
d = 0.8333333 mi/min * 6 min = 5 miles
