Answer:
$5400
$45
Step-by-step explanation:
Interest = principal x interest rate x time
principal = p
interest rate = 15%
time = 20/365 = 0.054795
Interest = 5445 - p
5445 - p = 0.15 x p x 0.054795
5445 - p = 0.008219p
Collect like terms and solve for p
p = $5400
Interest = 5445 - 5400 = $45
5x + 18 + 81 + 4x = 180
Like terms
9x + 99 = 180
9x = 81
X = 9
Hope this helps!
