P is inversely proportional to the square of q. When q = 2, P = 12.8 (a) Find a formula for P in terms of q.

P = 51.2/ q

Step-by-step explanation:

Given :

P α 1/q²

P = k/q²

k = constant of proportionality

P = 12.8 ; q = 2

12.8 = k /2²

12.8 = k / 4

k = 12.8 * 4

k = 51.2

Formuka for P in terms of q :

P = 51.2/ q

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
