Tracy deposited $59 into a bank account that earned 3.5% simple interest each year. If no money was deposited into or withdrawn
Illusion [34]

Answer

Find out the how much money was in the account after 1\frac{1}{2} years.

To prove

Formula

Simple\ interest = \frac{Principle\times Rate\times time}{100}

As given

Tracy deposited $59 into a bank account that earned 3.5% simple interest each year.

Principle = $59

Rate = 3.5 %

Time = 1\frac{1}{2}

i.e

Time = \frac{3}{2}

Time = 1.5 years

Put all the values in the equation

Simple\ interest = \frac{59\times 3.5\times 1.5}{100}

                                 =  \frac{309.75}{100}[/tex]

                                = $3.1(approx)

Amount in the account = Principle + Simple interest

                                      = $59 + $ 3.1

                                      = $ 62.1

1 Dollar = 100 cent

Now convert $62.1 into cent.

= 62.1 × 100

= 6210 cent

Therefore the money in the account is 6210 cent .

Find the largest possible revenue from the demand equation "Q= -2p + 1000
Mariana [72]
Revenue=quantity x price= (-2p+1000) (p)= -2p^2+1000p
The maximum revenue will occur when the first derivative is zero so when 2(-2p)+1000=0;p=250
Which generates 125,000 in revenue
Try prices of 245 and 255 and you will see they both are less than 250 thereby proving the max revenue is 250
