Answer:
122 students (Answer C)

122 students.
This corresponds to answer C. 122 students play an instrument.
Sally (1 person) took 5 hours. how long will it take 3 people?
5 hours / 3 people = 5/3 = 1 2/3
The answer is B
3 boxes of paper cost 3*21.99=65.97, 2 toner cartridges cost 2*52.90=105.8.
Given that there's 20% off for all office supplies, then 3 boxes of paper cost 3*$21.99*0.8=$52.78,
2 toner cartridges cost 2*$52.90*0.8=$84.64, the price of folder is $0.99*0.8=$0.792.
So, after buying these things given that there's 20% off for all office supplies, he will have only
$175-$52.78—$84.64= $37.58.
As 37.58/0.792=47.45, hence he can buy only 47 folders
Answer is 47
84 + x + 59 x + 51 =180
2x + 194 = 180
2x + 194 - 194 = 180 - 194 (subtract both sides by 194)
2x = -14
2x/2 = -14/2 (divide both sides by 2)
x = -7
