David borrows $15,000 for a new car. He is charged 6% simple interest per year. If he paid $4500 in interest, how many years did it take him to repay the loan?

Answers

Answer:

5 years

Step-by-step explanation:

Given that:

Amount borrowed = principal = p = $15000

Interest % per year = r = 6% = 0?06

Total Interest paid = $4500

Number of years it took to repay the loan (t) =?

Simple interest = (p * r * t)

4500 = (15000 * 0.06 * t)

4500 = 900t

4500 / 900 = t

5 = t

It tool 5 years to repay the loan

On 31 Jan 2021: Debit Interest expense for $250; Debit Note payable for $578.64; and Credit Cash for $828.64.

On 28 Feb 2021: Debit Interest expense for $247.11; Debit Note payable for $581.53; Credit Cash for $828.64.

Step-by-step explanation:

Note: This question is not complete. The complete question is therefore provided before answering the question as follows:

On January 1, 2021, Tropical Paradise borrows $50,000 by agreeing to a 6%, six-year note with the bank. The funds will be used to purchase a new BMW convertible for use in promoting resort properties to potential customers. Loan payments of $828.64 are due at the end of each month with the first installment due on January 31, 2021.

Record the issuance of the installment note payable and the first two monthly payments.

The explanation to the answer is now given as follows:

                          Note payable                                            50,000

                        (To record $50,000 borrowing through 6% Note from the bank.)

31 Jan 2021     Interest expense (w.1)        250

                         Note payable (w.2)            578.64

                            Cash                                                         828.64

                          (To record first month interest expense paid and part payment of $50,000 note.)

28 Feb 2021    Interest expense (w.4)       247.11

                         Note payable (w.5)            581.53

                             Cash                                                        828.64

                          (To record second month interest expense paid and part payment of $50,000 note.)

Workings:

w.1: Interest expense = First month interest expense = (Interest rate / 12) * Loan amount = (6% / 12) *$50,000 = $250

w.2: Note payable = First month part payment of note payable principal = Monthly payment - First month interest expense = $828.64 - $250 = $578.64

w.3: Loan balance after first month = Loan amount - First month part payment of note payable principal = $50,000 - $578.64 = $49,421.36

w.4: Interest expense = Second month interest expense = (Interest rate / 12) * Loan balance after first month = (6% / 12) *$49,421.36 = $247.11

w.5: Note payable = Second month part payment of note payable principal = Monthly payment - Second month interest expense = $828.64 - $247.11 = $581.53

Answer:

400$

Step-by-step explanation:

since he receives 20 percent of the sales and he receives 80 dollars. Then 80 dollars is 20 percent of the sales. Now, we can change 20 percent into a fraction, 20 percent is 20/100 or 2/10, now there are 5 twos in a ten so we multiply 2/10 by 5, since 2/10 right now is 80 dollars you multiply 80 by 5

80*5=400, so the sales of the week was 400 dollars

Hope this helps :)

Answer:

Thus, the sales of the week were $400

Step-by-step explanation:

Percentages

The salesman receives a 20% commission on all his sales.

One week the company pays $80 as commission.

This means that $80 corresponds to 20% of the sales.

To find the sales, we just divide the commission by the percentage (expressed as a decimal) as follows:

Sales = $80 / (20/100)

Sales = $80 / 0.20

Sales = $400

Thus, the sales of the week were $400

Hence proved

Angle between the pair of straight lines is zero therefore the lines are parallel.

What is parallel lines?

Parallel lines can be defined as two lines in the same plane that their angle of inclidation is equal and never meet.

Given,

x²+6xy+9y²-4x+12y-5=0

Comparing the equation with the general equation of 2nd degree

ax² + ay² + 2gx + 2fy + c = 0

so a=1, b=9, h= 3, g=-2, f=6, c=5

Angle between a pair of straight lines that is

tan∅=[tex]\frac{2\sqrt{h^{2} -ab} }{a+b}[/tex]

tan∅=[tex]\frac{2\sqrt{3^{2} -(1)(9)} }{1+9}[/tex]

tan∅=0°

∅=0°

Hence Angle between the pair of straight lines is zero therefore the lines are parallel.
