Let
x-------------> number of baseballs
y-------------> number of bats
we know that
x+y=100----------------> x=100-y --------------> equation 1
4.5x+20y=822 ------------------------> equation 2
<span>I substitute 1 in 2
</span>4.5*(100-y)+20y=822----------------> 450-4.5y+20y=822-----> 15.5y=372
y=372/15.5-----------> y=24
x+y=100------------> x=100-24---------> 76
the answer is
number of baseballs are 76
number of bats are 24

Explanation:
______________________
The total is "8/8" .
_______________________
If "5/8" of the total student population, the total that did NOT purchase a yearbook is:
"(8/8) − (5/8) = 3/8 " .
_____________________________
"3/8" = 3 ÷ 8 = 0.375

The answer is: " 0.375 " .

This is a very simple question. Observe and divide the last number "-24", you only get eight possibilities
{(-1, 24), (1, -24), (-2, 12), (2, -12), (-3, 8), (3, -8), (-4, 6), (4, -6)},
then try to figure out which is the only set that can get "2".
By the way, the answer is (6, -4).
