Answer:
623,459.79 and 224.51
Explanation:
first lets consider the first part of the problem and is how mucho do i need to accumulate for having an annuity for 25 years. this problem can be solved applying the concept of annuity, keep in mind that an annuity is a formula which allows you to calculate the present value of future payments affected by an interest rate.by definition the present value of an annuity is given by:
where 
is the present value of the annuity, 
is the interest rate for every period payment, n is the number of payments, and P is the regular amount paid. so applying to this particular problem, we have:
look at the value 25*12 because the problem tells us is during 25 years but the payment is monthly, and look at the 0.006 and it is comming from the APR/12 and we must do that because this rate is componded Monthly:
so for the second part we must calculate the second part we must calculate the acumulated value at 40 years of work:
where 
is the future value of the annuity, is the interest rate for every period payment, n is the number of payments, and P is the regular amount paid. so applying to this particular problem, we have:
solving for P we have:
P=224.51

Answer: He should decline production of the machine.
Explanation:
Analyzing the problem, we can determine if he should proceed or not by calculating the Net present value. That is present value of the machine in terms of perpetuity as it will be used forever and the cost incurred in its production.
Given the following ;
To manufacture $200 = 1 year, meaning
Amount or yearly payment = $200
Cost of machine = $2,000
Interest rate(r) = 11.5% = 0.115
Recall;
Present the value if perpetuity ;
(Payment per period ÷ rate)
= $200 ÷ 0.115 = $1739.13
Net present value = $1,739.13 - $2000 = - 260.87
Given the negative value of NPV, the cost outweighs the benefit, hence, he should decline.
Let the original price be x.
then,
x- 25% of x= 24
x- 25x/100 = 24
x- x/4=24
3x/4=24
3x= 96
x= 32
in short...the original price= 32 dollars
We might expect revenue will rise given that Phoenix is a large city.
<h3>What is a revenue?</h3>
This refers to the income generated from normal business operations which are calculated by average sales price * the number of units sold
Because Phoenix Suns decide to increase their ticket prices for next season, then, we might expect revenue will rise given that Phoenix is a large city.
