Ray Flagg took out a​ 60-month fixed installment loan of​ $12,000 to open a new pet store. He paid no money down and began making monthly payments of

​$221.

​Ray's business does better than expected and instead of making his

30th

​payment, Ray wishes to repay his loan in full. Complete parts ​a) through

​c).

Answers

Answer:

Since the question is incomplete, I looked for similar questions:

a) determine apr of installment loan  

b) how much interest will Ray save by paying off the loan early

c) what is the total amt due to pay off the loan?

a) first we will determine the effective rate:

PV annuity factor = loan / monthly payment

PV annuity factor = $12,000 / $221 = 54.2986

Using an annuity table, knowing that the number of periods is 60, we can see that the interest rate is 0.333%.

APR = 0.333% x 12 = 4%

b) I prepared an amortization schedule to determine Ray's balance after the 29th payment.

After the 29th payment, Ray's balance will be $6,498.54

in order to pay off the debt completely, he needs to pay $6,498.54 + $22.32 in interests = $6,520.86.

He will be able to save $331 in interests

c) $6,520.86

The area of a rectangular patio is 14 5/ 8 square meters. The width of the patio is 3 1/4 meters. What is the length? Enter your answer as a mixed number in simplest form. The length of the patio is meters.

Answers

Answer:

4 1/2 m

Step-by-step explanation:

Area of the patio = 14 5/8 m²

Width = 3 1/4m

Length = ?

Area of the patio = length ×width

Substitute

14 5/8 = 3 1/4 × L

Convert to improper fractions

117/8 = 13/4 L

Cross multiply

8 ×13L = 117×4

2 ×13L= 117

2×L = 9

2L = 9

L = 9/2

L. = 4 1/2 m (in mixed fraction)

Delta Company produces a single product. The cost of producing and selling a single unit of this product at the company's normal activity level of 88,800 units per year is: Direct materials $ 1.50 Direct labor $ 3.00 Variable manufacturing overhead $ 0.50 Fixed manufacturing overhead $ 4.45 Variable selling and administrative expenses $ 1.30 Fixed selling and administrative expenses $ 2.00 The normal selling price is $21.00 per unit. The company's capacity is 112,800 units per year. An order has been received from a mail-order house for 2,000 units at a special price of $18.00 per unit. This order would not affect regular sales or the company's total fixed costs

Answers

Answer:

The company should accept the special offer because it increases income by $23,400.

Step-by-step explanation:

Giving the following information:

Variable costs:

Direct materials $1.50

Direct labor $3.00

Variable manufacturing overhead $0.50

Variable selling and administrative expenses $1.30

Total variable cost= $6.3

An order has been received from a mail-order house for 2,000 units at a special price of $18.00 per unit.

Because it is a special offer and there is unused capacity, we will not take into account the fixed costs:

Effect on income= number of units*unitary contribution margin

Effect on income= 2,000* (18 - 6.3)

Effect on income= $23,400 increase

The company should accept the special offer because it increases income by $23,400.

The sum of the digits in a two digit number is 14. If you reverse and double the original number, and then add the result to the original number, the sum is 222. Find the original number

Answers

Answer:

Step-by-step explanation:

Let the two digits be x and y, where x is the tens digit and y is the units (ones) digit.

Then the number is 10x + y.

From the question,

The sum of the digits in a two digit number is 14,

That is, x + y = 14 ....... (1)

Also, from the question,

If you reverse and double the original number, and then add the result to the original number, the sum is 222

If the number is reversed, the new number will be 10y + x; and if this is doubled, we will get 2(10y + x).

Now, if this is added to the original number (10x + y), the sum is 222.

That is,

2(10y + x) + (10x + y) = 222

Then,

20y + 2x + 10x + y = 222

12x + 21y = 222 ........ (2)

Now, we will bring the two equations together and solve simultaneously.

x + y = 14 ....... (1)

12x + 21y = 222 ........ (2)

From equation (1)

x + y = 14

Then, x = 14 - y ...... (3)

Substitute the value of x in equation (3) into equation (2)

12x + 21y = 222

12(14 - y) + 21y = 222

168 - 12y + 21y = 222

168 + 9y = 222

9y = 222 - 168

9y = 54

∴ y = 54/9

y = 6

To determine x, substitute the value of y into equation (3)

x = 14 - y

∴ x = 14 - 6

x = 8

∴ x = 8 and y = 6

Recall that, the two digits are x and y, where x is the tens digit and y is the units (ones) digit.

Hence, the original number is 86.
