It is estimated that the average amount owed for student loans in 2010 was $25,250 per student. If the interest rate for student

loans increases to 6.8%, estimate how much more students will pay over a 10-year repayment period for this “average amount owed” as compared with

Let's fix 2010 as the present time. According to basic equations in engineering economy,

F = P (1+i)^n where F is the future worth, P is the present worth, i is the interest rate and n is the number of years. Substituting the appropriate values,

F = $25,250 (1 + 0.068)^10
F = $48,750

If the student has payed for the $25,250, then he needs to pay $48750 - $25250 = $23,500 more.

I hope I was able to help you. Thank you.

HELP ME!!! ITS DUE TOMMOROW!! Find the largest value of $r$ such that $6r^2+7r+8=6$.
Alex787 [66]
First you need to see that this is a quadratic. I need.to put all of the values on one side of equation to see what I got.
6r^2 + 7r + 8 = 6
6r^2 + 7r + 2 = 0

Now this one is difficult to factor so i will use quadratic equation:
[-b (+-) sqrt (b^2 - 4ac)] / (2a)

we know that a b and c are in a quadratic at these positions.
ax^2 + bx + c

so
[-7 (+-) sqrt (7^2 -(4)(6)(2)] / (2) (6)
[-7 (+-) sqrt (49 - 48)] / 12
[-7 (+-) 1] /12

split into the + and - for 2 answers
(-7 + 1) / 12
-6/12
-1/2

And
(-7 -1) /12
-8 / 12
-2/3

those are.the 2 answers

But but it says largest so -1/2
