I'm stuck on these now.

The state of Colorado is approximately rectangular shaped with perimeter 1,320 miles. Find the length (east to west) and width (north to south) if the length is 100 miles longer than the width.

An artist charges $15 for the frame and 75 cents per word for writing out the proclamation. If a city regulation does not allow gifts in excess of $150, what is the maxium number of words that can be written on the certificate?

A condominium owners cleared 114,600 on the sale of his condo, after paying 4.5% real estate commission. What is the selling price?

Thanks so much
 
Re: Word problems.

Draw a rectangle to represent the state of Colo.

Label the short side x.
Now label the long side in accordance with what the problem tells you about it, something about it being so much longer than the width.
Now, build your equation based on the fact that the perimeter of a rectangle is 2 times it width + 2 times its length.
Solve for x.
Now answer the question that was asked including miles, feet, or what have you.
Check your answer by using your answers in the original problem to see if it tells the truth. That is, is the length 100 miles more that the width. If you add up the measures of the 4 sides of the rectangle, do you get a total of 1320 miles?

Good luck.

First name things.

Width of rectangle = W

Length of rectangle( length is 100 miles longer than the width) = L = W + 100

Perimeter of rectangle = P = ??? (in terms of length of width)

Now the next step.....

An artist charges $15 for the frame and 75 cents per word for writing out the proclamation. If a city regulation does not allow gifts in excess of $150, what is the maxium number of words that can be written on the certificate?

How much money is left for words - after you took off money for frame = 150 - ????

A condominium owners cleared 114,600 on the sale of his condo, after paying 4.5% real estate commission. What is the selling price?

Name things -

selling price = S

Price cleared = selling price - commission

Thanks so much
