Keely says that he’s glad that his morning coffee is sold in a monopolistically competitive market rather than a purely competit
aleksklad [387]
This suggests that he buys products with higher prices than other similar products. But this type of market(monopolistic competition) is great though, because there are lesser suppliers than in the pure competition where products are almost within the same price ranges. In a monopolistic competition, suppliers sell their products with a justifiable high price. This is also an advantage for the buyers, they would be able to consume and be satisfied with products of high quality.

Describe the effect an increase in i, the interest rate applied to the present value, has on the monthly payment P in the formul
VARVARA [1.3K]

Answer:

B. An increase in i, the interest rate, will create an increase in P, the monthly payment.

Step-by-step explanation:

We have the formula for the monthly payment as,

P=\frac{i \times PV}{1-(1+i)^{-n} },

where P = monthly payment, i = rate of interest, PV = present value and n = time period.

Now, as i increase we get that (1+i) increases and so (1+i)^{n} increases.

This gives us that, \frac{1}{(1+i)^{n} } decreases and so 1-\frac{1}{(1+i)^{n}} decreases

Therefore, \frac{1}{1-(1+i)^{-n} } increases.

So, we get that as i increases , the value of P will increase.

Hence, option B is correct.

Zolol [24]

Subtract the sale price from the original price then divide the difference by the original price.

Guitar 1: 160 -100 = 60

60/160 = 0.375 x 100 = 37.5%

Guitar 2: 250 - 150 = 100

100/250 = 0.4 x 100 = 40%

The answer is the second guitar has a greater percent change of approximately 40%
