The repayment schedule is for a $1,300 loan at 7.5% for 6 months. What is the amount for interest at payment 5?
max2010maxim [7]

Answer: The answer is $2.77.


Step-by-step explanation:   Given that we have to pay the loan of $1300 at interest rate of 7.5% in 6 months. According to the table,

Amount for interest in payment 1 = $8.13,

Amount of interest in payment 2 = $6.79

and

Amount of interest in payment 3 = $5.45.

We can see here that the difference in the amounts to be paid in consecutive months will be same, i.e., the payments will form an arithmetic progression (A.P.).

The common difference = 8.13-6.79=6.79-5.45=1.34.

Therefore, amount of interest in payment 4 = $(5.45-1.34) = $4.11

and amount of interest in payment 5 = $(4.11-1.34) = $2.77.

Please see the attached modified table.

Thus, the answer is $2.77.

Wally's T-shirt company estimates the demand function for the Red sox world series t-shirt to be:
Zinaida [17]

Answer:costC(p)= 1400+20p

R(p)= 4p^2+200p

Profit= 4p^2+ 180p-1400

Step-by-step explanation:

q=4p+200

Student council charge $400 per week.

Revenue= price × quantity.

Relationship between revenue and profit= Revenue-total cost.

Total cost= cost of facilities +(cost of one shirt)× number of T-shirts sold per week.

C(p)= 400 + 5(q)

Put q=4p+200

C(p)= 400 + 5 (4p +200)

C(p)= 400+ 20p + 1000

C(p)= 1400+ 20p

Relationship between revenue and price=Revenue= price × quantity

R(p)= p×q

Put q=4p +200

R(p)= p ×(4p +200)

R(p)= 4p^2+ 200p

Profit= Revenue - total cos

Profit=R(p) -C(p)

Profit= (4p^2 + 200p) - ( 20p +1400)

Profit= 4p^2 + 180p -1400

The length of a rectangle is 3 cm less than its width what are the dimensions of the rectangle if its area is 270 cm²
kupik [55]

Given:

The length of a rectangle is 3 cm less than its width.

The area of the rectangle is 270 cm².

To find:

The dimensions of the rectangle.

Solution:

Let x be the width of the rectangle. Then,

\text{Length}=x-3

Area of a rectangle is:

\text{Area}=\text{Length}\times \text{width}

270=(x-3)(x)

270=x^2-3x

0=x^2-3x-270

Splitting the middle term, we get

x^2-18x+15x-270=0

x(x-18)+15(x-18)=0

(x-18)(x+15)=0

x=18,-15

Width of the rectangle cannot be negative. So, the only value of x is 18.

Width=18

Length=18-3

Length=15

Therefore, the length of the rectangle is 15 cm and the width of the rectangle is 18 cm.
