Answer:
13 children and 9 adults if the total cost is $152.5
Step-by-step explanation:
Let x children and y adults
x + y = 22 (1)
5.5x + 9y = 125.5 (2)
y = 22 - x
5.5x + 9(22 - x) = 125.5
5.5x + 198 - 9x = 125.5
-3.5x = 125.5 - 198
-3.5x = -72.5
x = 20.7
y = 22 - x = 1.3
Which is not possible
If the total cost is $152.5
x + y = 22 (1)
5.5x + 9y = 152.5 (2)
y = 22 - x
5.5x + 9(22 - x) = 152.5
5.5x + 198 - 9x = 152.5
-3.5x = 152.5 - 198
-3.5x = -45.5
x = 13
y = 22 - 13 = 9
It is A. We have a ratio of
900 workers : 3.2×10⁵
Dividing by 9×10² becomes
1 worker :

×10³
3.2/9 is just 0.36 rounded so it is
1 worker : 0.36×10³
or A
Answer:
3.5w
Step-by-step explanation:
I think it’s positive. As it gets heavier, the cost has a positive slope, or increases. I’m not absolutely sure though
