Judy currently has one credit card. She owes $500 and the credit card has a rate of 15%
per month. How much does Judy owe 8 months from now?

$ 1,100

Step-by-step explanation:

Well use the simple interest equation;

A = P(1 + rt)

Where:

   A = Total Accrued Amount (principal + interest)

   P = Principal Amount

   I = Interest Amount

   r = Rate of Interest per year in decimal; r = R/100

   R = Rate of Interest per year as a percent; R = r * 100

   t = Time Period involved in months or years

A = 500 (1 + 0.15*8)

A = 500 (2.2)

= 1100

  21.3

step-by-step explanation:

multiplying the given equation by c/sin(25°), we get

  c = 9/sin(25°) ≈ 21.2958 ≈ 21.3

we assume "c" is the length of ab, the side opposite angle c in triangle abc.

$5.41

step-by-step explanation:

$20 - $14.51 = $5.49.
