what is the final amount of 17.50 that is put into a saving account with 4 annual interest rate compounded yearly for 25 years?
pickupchik [31]
To find the total amount, you will use the formula for finding compounded interest.  This means you will be paid interest on top of the interest you have earned each year.

A = P(1 + r)^nt
P stands for the principal.
r is the interest rate when compounded annually
nt is the number of years

A = 17.50(1 + 0.04)^25
A = $46.65

This person would have $46.65 after 25 years.

Parker was able to pay for 44% of his college tuition with his scholarship.
WITCHER [35]
The total cost is $17,955.

Let x be the total amount of his tuition.  He paid for 44% of it, or 0.44, with his scholarship. This leaves 100%-44% = 56% = 0.56 of it to be taken care of with loans.  We know he took out 10054.52 in loans:

0.56x = 10054.52

Divide both sides by 0.56:
0.56x/0.56 = 10054.52/0.56
x = 17954.50 ≈ 17955

p varies directly as q and inversely as r. One set of values is p = 5, q = 1, and r = 2. Find p when q = 10 and r = 50.
Alexeev081 [22]
P = kq/r

5 = k*1/2
k = 2*5 = 10

p = 5*10/50 = 1
P is 1.
