If ?2000 is placed into a bank account that pays 3% compound interest per year , how much will be in the account after 2 years ?

Elodia [21]

Answer:

Step-by-step explanation:

A=P(1+r/n)^t*n

A=2000(1+.03)^2

A=2000(1.03)^2

A=2000(1.0609)

A=2121.80

Since it’s per year I didn’t divide 1 by .03 or multiply it by 2 since it would end in the same equation. If you were to do semiannually or any other payment period, the process would have been nessassary.

Hope this helps!

3. At a bargain store, Jamal bought 2 items that each cost the same amount. Isaiah bought 3 items that each cost the same amount

coldgirl [10]

Answer:

$6.75 and $4.50

Step-by-step explanation:

a) Jamal spent:

Isaiah spent:

3 (x - 2.25)

The equation is:

2x = 3(x - 2.25)

b) Solving the equation

2x = 3x - 6.75
3x - 2x = 6.75
x = 6.75

c) Jamal's items cost

$6.75 each

Isaiah's items cost

$6.75 - $2.25 = $4.50 each
