For this case we have the following variables:
 P = area covered by a roll of wallpaper
 w = the total area of the walls
 n = number of rolls to buy
 We write the equation for n.
 You must take into account that you can determine this amount by dividing the total area between the area covered by each roll of paper.
 We have then:
 n = w / P
 
 Answer:
 
a formula that will help them determine how much wall paper they'll need to purchase is:
 n = w / P

Sam scored 59, 64, and 68 on three tests. How many points should he get on the fourth test to get an average score of 70? A. 63.
olga2289 [7]
To find this out the easy way, add up all the numbers and an answer, then divide by 4.
59 + 64 + 68 + 63.67 = 254.67
254.67/4 = 63.66
A is not correct.
59 + 64 + 68 + 65.25 = 256.25
256.25/4 = 69.25
B is not quite correct.
59 + 64 + 68 + 75 = 266.
266/4 = 66.5
C is not correct.
59 + 64 + 68 + 89 = 280
280/4 = 70.
D.) is the correct answer.
I hope this helps!
