2 hours = 45 pages
1 hour = 45 ÷ 2 = 22.5 pages
12 hours = 22.5 x 12 = 270 pages
Answer; 270 pages
(5 Neighbors) x (($1.00 Box) + (? Plant) + ($3.00 Gloves)) = 42.50
5 x (1 + x + 3) = 42.50
Combine in parens.
5 x (4 + x) = 42.50
Distribute.
20 + 5x = 42.50
Subtract 20 from both sides.
5x = 22.50
Divide both sides by 5.
x = 4.50
Thats the cost of each plant.
Check.
5 x (1 + 4.50 + 3)
5 x 8.50 = 42.50

Step-by-step explanation:
B is the only answer that will ensure she gets graduate students in the sample without getting too few or too many.
Answer:
140 + 184 + 165 + 326 = 815/4 = 203.8
86 + 36 + 45 + 126 = 293/4 = 73.3
14 + 36 + 9 + 84 = 143/4 = 35.8
9 + 6 + 7 + 4 + 3 + 6 = 35/6 = 5.8
25 + 42 + 59 + 62 + 18 = 206/5 = 41.2
