Kyoko is a hard-working college senior. One Saturday, she decides to work nonstop until she has answered 150 practice problems f

or her math course. She starts work at 8:00 AM and uses a table to keep track of her progress throughout the day. She notices that as she gets tired, it takes her longer to solve each problem.
Time
Total Problems Answered
8:00 AM 0
9:00 AM 60
10:00 AM 105
11:00 AM 135
Noon 150
Use the table to answer the following questions.
The marginal, or additional, benefit from Kyoko’s second hour of work, from 9:00 AM to 10:00 AM, is
45
problems.
The marginal benefit from Kyoko’s fourth hour of work, from 11:00 AM to noon, is
15
problems.
Later, the teaching assistant in Kyoko’s math course gives her some advice. “Based on past experience,” the teaching assistant says, “working on 52.5 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 her 4 hours of study time to get the best exam score possible, how many hours should she have spent working on problems, and how many should she have spent reading?

1 hour working on problems, 3 hours reading
2 hours working on problems, 2 hours reading
3 hours working on problems, 1 hour reading
4 hours working on problems, 0 hours reading

andrew11 [14]

Answer:

23.25%; 62.01%

Explanation:

(a) Amount received:

= No. of shares × selling price

= 100 × $43

= $4,300

Sales deposit = 60% of Amount received

                        = 0.6 × $4,300

                        = $2,580

Amount paid = No. of shares × Purchase price

                      = 100 × $49

                      = $4,900

Therefore, Loss = $4,900 - $4,300

                           = $600

(b) If buys at $27, then

Amount paid = $27 × 100

                     = $2,700

Profit = $4,300 - $2,700

         = $1,600

Loss on investment:

= ($600 ÷ $2,580) × 100

= 23.25%

Profit on investment:

= ($1,600 ÷ $2,580) × 100

= 62.01%

UNO [17]

Answer:

the present value is $13,588.97

Explanation:

The computation of the present value of the retreading operation is shown below:

As we know that

Present value = Future value ÷  (1 + rate of interest)^time period

= $2,700 ÷ 1.09^1 + $2,700 ÷ 1.09^2 + $2,700 ÷ 1.09^3 + $2,700 ÷ 1.09^4 + $2,700 ÷ 1.09^5 + $2,700 ÷ 1.09^6 + $2,700 ÷ 1.09^7

= $13,588.97

Hence, the present value is $13,588.97
