Suppose that Marlie had decided to apply for a private loan rather than a federal loan. She has
34kurt

Using simple interest, and considering a loan of $5,000, it is found that:

a) Her monthly payment is of $74.17.

b) She will pay back $8,900.

c) The total interest amount is of $3,900.

The amount of money after <u>t years</u> in <em>simple interest</em> is modeled by:

A(t) = A(0)(1 + rt)

In which:

  • A(0) is the initial amount.
  • r is the interest rate, as a decimal.

In this problem:

  • The loan is of $5,000, hence A(0) = 5000.
  • The APR is of 7.8%, hence r = 0.078
  • 10 years, hence n = 10

Item b:

A(10) = 5000[1 + 0.078(10)] = 8900

She will pay back $8,900.

Item a:

$8,900 will be paid in 10 x 12 = 120 months, hence:

M = \frac{8900}{120} = 74.17

Her monthly payment is of $74.17.

Item c:

<u>Loan of $5,000, pays back $8,900</u>, hence:

8900 - 5000 = 3,900

The total interest amount is of $3,900.

find the sum of the arithmetic sequence. -10, -7, -4, -1, 2, 5, 8 select one: a. 11 b. -70 c. 0 d. -7
OLga [1]
This is an aritmetic series;
a=-10
d=-7--10
d=3
n= 7
Sum=\frac{n}{2}(2a+(n-1)d)
Sum=\frac{7}{2} (2*(-10)+(7-1)3)
sum=3.5(-20+18)
sum=3.5(-2)
sum=-7
