If you purchased 450 shares of Apple stock 3 years ago for $112.30 per share and you paid 4%
commission for the purchase. How much was the total purchase cost you?

Answers

Answer: $52556.40

Step-by-step explanation:

Price per share = $112.30

Number of shares = 450

Cost of the shares = 450 × $112.30 = $50535

Since there is a 4% commission, the total cost of the purchase will be:

= $50535 + (4% × $50535)

= $50535 + (0.04 × $50535)

= $50535 + $2021.40

= $52556.40

What is lifetime cap?

Answers

Answer:

What is a life cap?

A life cap, or lifetime cap or rate cap, is the maximum amount that a borrower’s interest rate can increase over the term of the loan. The life cap represents either a total absolute rate or percentage change in the rate.

Deeper definition

Adjustable-rate mortgages (ARMs) usually come with a series of caps that limit how much interest can be charged to the borrower after the fixed-interest period ends. The initial adjustment cap limits the change in interest for the first time rates are adjusted, and there are subsequent, or periodic, interest caps to cover upcoming changes in the interest rate.

Life caps limit how much interest the lender can charge over the term of the entire term. Usually expressed as an absolute percentage, or a change in percentage, life caps may differ between lenders but should be spelled out in the loan agreement.

Lifetime caps represent the highest rate at which interest can be charged. However, ARM interest rates can actually decrease after the fixed-interest period. Additionally, lifetime caps don’t affect other costslike transaction and late fees, which are factored along with the interest rate into the annual percentage rate (APR).

Wondering how a life cap will affect your payments? Use Bankrate’s mortgage calculator to find out how much you’ll owe.

Life cap example

James acquired a loan from a bank with 7 percent as the initial interest rate. The bank allows adjustments every three months, but has a life cap of 3 percent. Therefore, the maximum interest rate Jack will ever have to pay is 10 percent.

There you go

Answer: A) A limit on how much an ARM's interest rate can change over the

life of a mortgage.

What is the radius of the cone in the diagram? Round your answer to the nearest whole number.

Answers

Answer:

4

Step-by-step explanation:

R= 4Units


Step-by-step Explanation:

Volume of the cone = 101.06 Cubic Units
Height (h) = 12 Units
Radius (r) = ?

Thus formula, for volume of the cone = 1/3 *πr2h

(Plug in the values and solve for r):
1/3*π*r2* 12 = 201.06
r2*4 *π = 201.06
r2* 12.57 = 201.06


(Divide both steps by 12.57):
r2 = 201.06/12.57
r2 = 15.9952267
r = [15.9952267
r = 4 Units

Jon is taking a 625 mile trip. On the first day, he drove 183 miles.

How many more miles does he have to drive?


Answers

Answer:

442

Step-by-step explanation:

625-183=442

The more miles he have to drive is 442miles.

We have given that,Jon is taking a 625 mile trip.On the first day, he drove 183 miles.

We have to find the how many more miles does he have to drive.

What is the formula for the total miles drive?

Total distace mile drove =mile drove first day+Remaining drove in miles

So we can write it as,

Total distance  miles-Miles drove first day= Remaining miles

Total distance=625

first day distance=183

Remaining distance

=625-183

=442

Therefore the remaining distance is 442miles.
