The average interest gained from three accounts in one year is $913.224
<u>Explanation:</u>
Given:
Bank A:
Principal, P₁ = $250.67
Rate, r₁ = 12 %
Bank B:
Principal, P₂ = $765.13
Rate, r₂ = 7 %
Bank C:
Principal, P₃ = $28500.36
Rate, r₃ = 9 %
Interest from Bank A:
Interest from Bank B:
Interest from Bank C:
Average interest gained from three accounts in one year :
Therefore, average interest gained from three accounts in one year is $913.224
I guess irreducible form? (translated from my language, maybe it's actually another word?)
Answer:
both answer is 31°
Hope it is helpful for you
