Answer: Can you show the full question.
Step-by-step explanation:
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
12 hours (5880 divided by 490)
