Answer:
x - 6
Step-by-step explanation:
First, put each grade in terms of x. Most grades are compared to Sophomores, so I made that x
Freshmen = x + 10
Sophomores = x
Juniors = x + 20
Seniors = (x + 10) + 7 = x + 17
Then, the total number of students = 363, so we’ll make an equation that adds them all up in terms of x to equal 363
(x + 10) + x + (x + 20) + (x + 17) = 363
Combine like terms:
4x + 47 = 363
Subtract 47 from both sides:
4x = 316
Divide both sides by 4:
x = 79
The question was how many seniors there are. Seniors were x + 17, so 79 + 17 = 96
Starting price is 2.65, increased by .56
2.65+.56=3.21
Price is 3.21, decreased by .23
3.21-.23=2.98
Price is 2.98, increased by 1.02
2.98+1.02= 4
Price is 4, decreased by .48
4-.48=3.52
Now find the difference from the starting price (January) from the end price (May)
3.52-2.65=.87
<u>The difference from gas prices is $.87</u>

Answer:
"the sample is biased because it does not represent the population." and "The question is biased toward a Yes response."
Step-by-step explanation:
The sample is biased because they people being surveyed are shopping at a sporting shop so most of them are going to support it.
The question is biased because it says "outdated" and "modern" to try to get people to support it.
