You deposit $2200 Into three separate bank accounts for each pay 3% annual interest. How much interest does each account earn af
Hatshy [7]

The formula to find the amount is

A=P(1+r)^n

Here A = amount

P is the principal

r is the rate

n is the number of years

Then to find the interest we subtract principal from amount.

Interest = A - P

Here

P= 2200, r = 3% = 0.03 , n = 6 years

A = 2200 (1+0.03)^6=2626.92

Hence the interest earned = 2626.92-2200 = $426.92

Now if the total of $2200 was deposited in three banks then each account earns \frac{426.92}{3}= 142.31

Each account earns $142.31

● Answer:

b) 24 cm

● Step-by-step explanation:

l + 4 = 2w => l = 2w - 4

5w + 6 = P => 5w + 6 = 2w + 2l

5w + 6 = 2w + 2(2w - 4)

5w + 6 = 2w + 4w - 8

6 + 8 = 6w - 5w

w = 14

l = 2x14 - 4

l = 28 - 4

l = 24 cm
