Answer:
2.5
Step-by-step explanation:
It looks like it's 2.5.
24.4/4 =6.1 hours daily is the average hour per day
The answer is Y=11, X=-1
Here's my work:
x=-12+y
-6(-12+y)+2y=28
6*12= 72
72 -6y +2y=28 (now we combine like-terms)
72-4y=28 (now divide by -4)
-18+y=-7 (add 18 to both sides)
y=11
next part we find x:
x=-12+(11)
x=-1
95/20 = $4.75 for each student.
$4.75 * 20 = $95
So: $4.75*162 = $769.50
