Let the two numbers be x and y.
The difference between the numbers is 4. Therefore
x - y = 4 (1)
The sum of one-half of each number is 18, therefore
x/2 + y/ 2 = 18
x + y = 36 (2)
Add equations (1) and (2).
(x - y) + (x + y) = 4 + 36
2x = 40
x = 20
From (2), obtain
y = 36 - x = 36 - 20 = 16.
Answer: The two numbers are 16 and 20.
A) 2277 = 110% of number in 2013
b) Number in 2013 = 90% of year before, 2012
2277 = 110% of Number in 2103
2277 = (110/100) * Number in 2013
2277 * 100/110 = Number in 2013
2070 = Number in 2013
Number in 2013 is = 2070
b) Number in 2013 = 90% of year before, 2012
2070 = (90/100) * Number in 2012
2070 * 100/90 = Number in 2012
2300 = Number in 2012
Hence number in 2012 = 2300 student athletes.
