The ration is 28:1 and 11:7
I would rewrite the question then show how you got your answer
Answer:
10.50 is the interest
Step-by-step explanation:
B = p(1 + r)^t
P = 50
r = .10
t = 2
B = 50(1 + .1)^2
= 50(1.1)^2
= 50(1.21)
= 60.5
But we want to know the interest and this is the balance
60.5- 50 = 10.5
They're equal length, so add 18 and 18 to get 36.
