Answer:

Examples of confidentiality:

The channel of communication between the Bank and Automated Teller Machine must be encrypted. The personal identification number (PIN) of the ATM'S Card must also be encrypted as well, if stored

Examples of integrity:

The actions accomplished through the Automated Teller Machine must be linked to the bank account link with the ATM Card

Examples of availability requirements:

At any time, the Automated Teller Machine system must serve at least X concurrent bank users. The ATM system must be available at most 99.99% of the time.

The Valenti Company uses flexible budgeting for cost control. Valenti produced 10,800 units of product during October, incurring
Alex Ar [27]

Answer:

$500 favorable

Explanation:

Given;

Number of units produced  = 10,800 units

Actual indirect material costs = $13,000

Reflected indirect material costs for 144,000 units  = $180,000

Now,

Per unit reflected indirect material costs = $180,000 ÷ 144,000

= $1.25 per unit

Therefore,

Budgeted indirect material cost for actual units produced

= $1.25 × 10,800

= $13,500

since,

the budgeted cost for indirect material cost for actual units produced is more than the actual indirect material cost, therefore

the indirect material costs in October is favorable

amount = Budgeted cost - Actual cost

= $13,500 - $13,000 = $500 favorable

A heat integration project results in saving 5 MM Btu/h of heating utility and 14 MM Btu/h of cooling utility. The prices of hea
guapka [62]

Answer:

9.24 yr

Explanation:

The payback period refers to the amount of time it takes to recover the cost of an investment. In order to find a payback period we need to go through some calculations first  

Annual savings =  5 MM Btu/hr x 8,000 hr/yr x $4/MM Btu x 14 MM Btu/hr x  8,000 hr/yr x $7/MMBtu

Annual savings = $0.944 MM/yr

TCI = \frac{4.0 MM}{0.85}

TCI = $4.7 MM

Depreciation - Annualized fixed cost = \frac{[4.0 - 0] }{10}

Depreciation - Annualized fixed cost = $0.4 MM/yr

Total cost annualized = Annualized fixed cost + Annual operating cost

Total cost annualized = 0.4 + 0.5

Total cost annualized= 0.9 MM/yr

Annual net (after-tax) profit = Annual income - Total cost annualized x (1-Tax rate + Depreciation

Annual net (after-tax) profit = $0.944 MM/yr - $0.9 MM/yr x  1 -0.25 + $0.4 MM/yr

Annual net (after-tax) profit = 0.433MM/yr

Payback period = \frac{4.0}{0.433MM/yr}

Payback period = 9.24 yr

Milano Co. manufactures and sells three products: product 1, product 2, and product 3. Their unit selling prices are product 1,
Andrei [34K]

Answer:

1. break even number in units = $270,000 / $12 = 22,500

product 1 units = 22,500 x 6/12 = 11,250 units

total sales = 11,250 x $40 = $450,00 0

product 2 units = 22,500 x 4/12 = 7,500 units

total sales = 7,500 x $30 = $225,000

product 3 units = 22,500 x 2/12 = 3,750 units

total sales = 3,750 x $20 = $75,000

total sales = $750,000

2. break even number in units = $320,000 / $18.67 = 17,139.8 units

product 1 units = 17,139.8 x 6/12 = 8,569.9 ≈ 8,567 units

total sales = 8,567 x $40 = $342,680

product 2 units = 17,139.8 x 4/12 = 5,713.27 ≈ 5,714 units

total sales = 5,714 x $30 = $171,420

product 3 units = 17,139.8 x 2/12 = 2,856.63 ≈ 2,857 units

total sales = 2,857 x $20 = $57,140

total sales = $571,240

c. Management should start using the new material as soon as possible since it doesn't only decrease the break even point, if sales level remain the same, it will increase operating profits.

Explanation:

product 1's contribution margin = $10

product 2's contribution margin = $15

product 3's contribution margin = $12

sales mix = 6:4:2

weighted contribution margin = ($10 x 6/12) + ($15 x 4/12) + ($12 x 2/12) = $5 + $5 + $2 = $12

new contribution margin:

product 1's contribution margin = $20

product 2's contribution margin = $20

product 3's contribution margin = $12

sales mix = 6:4:2

weighted contribution margin = ($20 x 6/12) + ($20 x 4/12) + ($12 x 2/12) = $10 + $6.67 + $2 = $18.67
