Rita charged $126 for a dvd player at an interest rate of 15.9%. how much will rita have to pay after 2 months if she makes no payments?

$ 129.34 will be the total payment made after two months if she made no initial payment

Step-by-step explanation:

annual interest rate = 15.9 %

initial charge = $126

to get the annual interest paid = 15.9% of $126

                                                   = 0.159 * $126 = $20.03

monthly interest paid would be = annual interest  / 12 months

                                                     = 20.03 / 12 = $1.67

hence in 2 months Rita will pay = initial charge + monthly interest * 2

                                                     = $126 + $ 1.67 *2 = $ 126 + $3.34

                                                     = $ 129 .34

Interest rates are always given an annual interest rate.

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
