I'd start with setting up the equations. Calling x the number of students in most popular country 1, and y in country 2.
x + y = 44740
x - y = 5672
now solve for x1 and x2. You can subtract second from first:
0 + 2y = 39068
y = 19534
so
x = 5672 + 19534 = 25206
Add a sentence to answer it in words.
5x + 2y=50
or
5x + 2y<=50 (less than or equal to)
then
x + 2y=30
or
x + 2y<=30(less than or equal to)
Well i may be wrong but is jack dropped it 3 feet above that wouldnt count as part of the depth the depth would start once it hits the water. so 14-3 equals 11. the depth is 11 feet. 11 is an integer. if that makes sence
