Answer:
The answer is below
Step-by-step explanation:
Let us assume the rate of printing in machine A is x per hour and the rate for machine B is y. Given that machine B prints at half the rate of machine A, therefore:
y = (1/2)x (1)
Also, both machine produces 200 newspaper printouts, and both operate at different times for a total of 4 hours. Therefore:
200/x + 200/y = 4 (2)
Put y = (1/2)x in equation:
Put x = 150 in equation y:
y=(1/2)150 = 75
Therefore the rate of machine A is 150 newspapers per hour while that of machine B is 75 newspapers per hour

Using <span>Compound interest formula:
</span>
<span><span>The exponential function for calculating the amount of money after <span>t <span>years, <span>A<span>(<span>t<span>), where<span> P <span>is the initial amount or principal, the annual interest rate is <span>r <span>and the number of times<span> interest is compounded per year is n, is given by

</span><span>from the given information:
p = 2,310 , r = 0.035 ,
</span><span>compounded daily ⇒⇒⇒ n =365
To calculate the time : </span>deposited April 12 and withdrawn July 5<span>
t = 2 months and 23 days = 83 days = 83/365 years
∴ n t = 365 * 83/365 = 83
