Scrooge mcduck deposits $200,000 into two simple interest accounts. the annual simple interest rate on one account is 2%. the annual simple interest on the second account is 3%. how much should be invested in each account so that the total interest earned is $5,550 at the end of one year?

Step-by-step explanation

There are two accounts.

Let, in the account of rate 2%,

he should deposit  x

So, for the account of rate  3%,

he should deposit    200000-x ,

Because the total deposits is  200000

Now, from the simple interest formula we know,

I=Pnr

where, I is the interest, P is the capital,

n is the time and r is the rate.

So, for the account of  2% rate , we get

r=2%=2/100=0.02

n=1 year

P=x

So, interest,

I=Pnr

=x (1) (0.02)

=0.02 x

And for the account of rate 3% we get

I=(200000-x) (1) (0.03)

=6000-0.03x

Total interest is  $5550

So,

According to question,

0.02x+6000-0.03x=5550

or, -0.01x=5550-6000

or, -0.01x=-450

or, x= -450 / -0.01

     =45000

Now,

200000-45000=155000

So, he should deposit  $45000 at  2% rate

and   $155000  at 3% rate

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all

the eight graders whould be the answer
