First, let's declare a variable
x = # of students
Now, let's create an equation to model the problem.
x * 0.273 = 125
Divide both sides by 0.273
x = 457.8 = 458 students.
Note, I rounded to the nearest whole number.
11,15,19,23
an = 11 + 4(n-1)
an = 11 + 4n - 4
an = 4n + 7
10 would be the answer I believe.
This would be 525 / 0.70 = $750 Answer
710,000 the thousands column is less than 5 therefore the answer is 710,000
