Part A

Sue

A = P*(1+r/n)^(n*t) is the compound interest formula

A = 2300*(1+0.024/1)^(1*3)

A = 2469.6061952

A = 2469.61

A - P = 2469.61-2300 = 169.61

<h3>Sue gets 169.61 pounds in interest</h3>

-----------

Bill

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

A = 1800*(1+0.034/1)^(1*3)

A = 1989.9131472

A = 1989.91

A-P = 1989.91-1800 = 189.91

<h3>Bill earns 189.91 pounds in interest</h3>

Bill has earned more in interest.

=====================================================

Part B

By year 2, Bill has 1924.48 pounds in his account based on the work shown below

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

A = 1800*(1+0.034/1)^(1*2)

A = 1924.4808

A = 1924.48

This amount is the new deposit, so to speak, when we change the interest rate. Now r = 0.034 changes to r = 0.04. We only go for one year so t = 1

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

A = 1924.48*(1+0.04/1)^(1*1)

A = 2001.4592

A = 2001.46

Bill has 2001.46 pounds in his account after 3 years if the interest rate for the 1234 account changes to 4% in the third year.

Now subtract off the original amount Bill deposited to get

2001.46-1800 = 201.46

For this scenario, Bill earns 201.46 pounds in interest.

Therefore, Bill has earned the most interest for both cases of the interest rate staying at 3.4% or changing to 4% for that third year.

Solve y-12/25=3 1/5. What number is y?<br><br> A. 3 1/5<br> B. 3 17/25<br> C. 3 7/25<br> D. 4 17/25
kicyunya [14]

Answer:

Option c) y=3\frac{17}{25} is correct

The value of y is 3\frac{17}{25}

Step-by-step explanation:

Given equation is  

y-\frac{12}{25}=3\frac{1}{5}

To solve the given equation for y

y-\frac{12}{25}=3\frac{1}{5}

y-\frac{12}{25}=\frac{16}{5}  (converting mixed fraction to normal fraction )

y-\frac{16}{5}=\frac{12}{25}

y-\frac{(16\times 5)+12}{25}  (taking LCM 25 )

=\frac{80+12}{25}  (adding the terms )

y=\frac{92}{25}  (now convert fraction into mixed fraction )

Therefore y=3\frac{17}{25}

Option c) y=3\frac{17}{25} is correct

The value of y is 3\frac{17}{25}
