Barry and Iris Allen want to save money for their children. They deposit $2500 each year for 20 years in a savings account paying 5% compounded annually.

a. How much would be in the account after 20 years?

b. How much of the final balance did they actually contribute?

A). The amount in 20 years

=$ 13574.45

B).36.83%

Step-by-step explanation:

A)

The both deposit the sum of $2500 each year that is the sum total of $5000.

Rate = 5 %

Years= 20

Then compounded annually so number of times = 20

A = P(1+r/n)^(nt)

= 5000(1+ (0.05/20))^ (20*20)

= 5000(1+0.0025)^(400)

= 5000(1.0025)^(400)

= 5000(2.71489)

= 13574.45

The amount in 20 years =$ 13574.45

B) let's calculate the percentage of the actual balance they contributed.

= 5000/13574.45

= 0.3683333

= 36.83%

e2020 got it right

the correct answer is a) they believe they have a "just cause."

islamic terrorists justify their violent actions because they believe they have a "just cause."

every act of terrorism of islamic sects is done “in the name of allah”. that justifies their actions. islam people who commit those terrorist attacks are not afraid to die. that is why the attacks have horrible consequences. they know they are going to die and they are proud to do it because it is in the name of allah, so it is justified and is for a “good cause.”

since the very beginning of the conflict with israel, islam is fighting a “sacred war”, respecting the words stated in the qur’an. they fight against the domination of the western countries and to defend their occupied territories.
