A decision at the marginVan is a hard-working college senior. One Thursday, he decides to work nonstop until he has answered 200

practice problems for his economics course. He starts work at 8:00 AM and uses a table to keep track of his progress throughout the day. He notices that as he gets tired, it takes him longer to solve each problem.Time Total Problems Answered8:00 AM 09:00 AM 8010:00 AM 14011:00 AM 180Noon 200The marginal, or additional, gain from Van’s first hour of work, from 8:00 AM to 9:00 AM, isproblems.The marginal, or additional, gain from Van’s second hour of work, from 9:00 AM to 10:00 AM.The marginal gain from Van’s third hour of work, from 10:00 AM to 11:00 AM, isproblems.Later, the teaching assistant in Van’s economics course gives him some advice. "Based on past experience," the teaching assistant says, "working on 30 problems raises a student’s exam score by about the same amount as reading the textbook for 1 hour." For simplicity, assume students always cover the same number of pages during each hour they spend reading.Given this information, in order to use his 4 hours of study time to get the best exam score possible, how many hours should he have spent working on problems, and how many should he have spent reading?a. 1 hour working on problems, 3 hours reading.b. 2 hours working on problems, 2 hours reading.c. 3 hours working on problems, 1 hour reading.d. 4 hours working on problems, 0 hours reading.

Answer and Explanation:

1. The extra gain arises from Van first work hour i.e. from  8:00 AM to 9:00 AM is

= 80 - 0

= 80

2. The extra gain arises from Van third work hour i.e. from  10:00 AM to 11:00 AM is

= 180 - 140

= 40

3. He should select 3 hours of working and 1 hour reading as at the fourth hour for problem solving, he solves only

= 200 - 180

= 20

That brings better off study at it depicts the worth of 30 solving problems

Vincent operates a scenic tour business in Boston. He has one bus which can fit 50 people per tour and each tour lasts 2 hours.
mixas84 [53]

Answer:

There is some information missing, and when I looked for it I found similar questions but the demand was already given and the question was about Vincent's total daily income.

Passenger                  Price                  Daily demand

Adults                          $18                        70

Children                      $10                        25

Senior citizens            $12                        55

total                                                           150

total revenue per day = ($18 x 70) + ($10 x 25) + ($12 x 55) = $1,260 + $250 + $660 = $2,170

total operating costs per day = (150 / 50) x $450 = $1,350

operating income per day = $2,170 - $1,350 = $820

When calculating the marginal revenue and marginal profit in this problem, use the approach given for the marginal cost and marg
Elena-2011 [213]

The question is incomplete. The complete question is :

A manufacturer of mountain bikes has the following marginal cost function:

                                           $C'(q)=\frac{700}{0.7q+8}$

where q is the quantity of bicycles produced.

When calculating the marginal revenue and marginal profit in this problem, use the approach given for the marginal cost and marginal revenue in the discussions in your textbook.

a) If the fixed cost in producing the bicycles is $2800, find the total cost to produce 30 bicycles?

b) If the bikes are sold for $200 each, what is the profit (or loss) on the first 30 bikes?

Solution :

Given :

$C'(q)=\frac{700}{0.7q+8}$

a). Fixed cost, FC = $ 2800

Total cost to produce 30 bicycles is :

 $C = 2800 + \int_0^{30} C'(q) \ dq$

      $ = 2800 + \int_0^{30} \frac{700}{0.7q+8} \ dq$

     $= 2800+700\left[\frac{\ln (0.7q+8)}{0.7}\right]^{30}_0$

     $=2800+1000[\ln ((0.7 \times 30)+8)- \ln 8 ]$

     $= 2800 +1000 [\ln 29 - \ln 8]$

    = 2800 + 1287.85

    = $ 4087.85

b). Total selling price = $ (200 x 30)

                                   = $ 6000

    Profit  =  6000 - 4087.85

                = $ 1912.15
