A rug is to fit in a room so that a border of even width is left on all four sides. if the room is 22 feetby 25 feet and the are
Damm [24]
--------------------------------------------------------
Find area of the border :
--------------------------------------------------------
Area of the room = 22 x 25 = 550 ft²
Area of the rug = 238 ft²
Area of the border = 550 - 238 = 312 ft²

--------------------------------------------------------
Define y:
--------------------------------------------------------
Let the width be y.

--------------------------------------------------------
Find area of the border in term of y :
--------------------------------------------------------
The area of the border =  22y x 2 + 25y x 2 - 4y² = 94y - 4y²
*We need to take away 4y² because the 4 corners will be overlap twice if we don't.

--------------------------------------------------------
Solve y :
--------------------------------------------------------
94y - 4y² = 312
4y² - 94y + 312 = 0
2y² - 47y + 156 = 0 
<span>(y - 4)(2y - 39) = 0
</span>y = 4 or y = 19.5
 
--------------------------------------------------------
Answer: The border can be 4 ft or 19.5 ft

Can someone please help me with this?

So first, you should try to write an equation to fit the problem.

You know Alice already read 91 pages. That number won't be affected by the variable, d, the number of days. 91 is your constant that will be added to the part affected by your variable.

You also know Alice is reading 15 books everyday. That number  will increase by 15 with every day that passes, so the expression 15d can be used to find how many books she has read since she has decided to continue the book.

You know p is the total number of pages she has read, so set p equal to the sum of the the number of books read every day + the constant (number of books she has already read):
p = 15d + 91

Now put values in for d to find p:
When d = 2, p = 15(2)+91 = 121
When d = 4, p = 15(4)+91 = 151 
When d = 6, p = 15(6)+91 = 181
When d = 8, p = 15(8)+91 = 211

So your answers are:
121
151
181
211
