Thread: Algebra question

P dollars is invested at annual interest rate for 1 year. if the interest is compounded semiannually, then the polynomial p(1+r/2)^2 represents the value of the investment after 1 year. could you rewrite this expression without parentheses. Evaluate the polynomial if p = $200 and r = 10

p(1+r/2)^2
plug in:
p = $200 and r = 10

$200(1+10/2)^2

$200(1+5)^2

$200(6)^2

$200(36)

$7200

make sense?
