Mark is saving for his son's college education. If the savings account earns 9% interest compounded quarterly, and he wants to have $80,000 in 18 years, what must the principal be?

The answer is $16119 my friend!

Step-by-step explanation:

A = p(1+r/n)^nt

80000 = p(1+0.09/4)^4x18

80000 = p(1.0225)^72

p = 16118.74

“ a line segment that has the endpoints on the circle and passes through the midpoint is called the diameter. the diameter is twice the size of the radius. a line segment that has its endpoints on the circular border but does not pass through the midpoint is called a chord. a circle is the same as 360 small circle up the number 0 . i hope this .
