Answer:
Was the growth rate of 5.2% for the starting hour or after the 25 hours
Step-by-step explanation:
Simultaneous Equations
3x + y = 4
5x - y = 22
The signs of the matching values aren't the same so we add the rest of the equations.
8x = 26
Divide both sides by 8 to get x = 3.25
Now substitute back into the first equation.
(3 x 3.25) + y = 4
9.75 + y = 4
Subtract 9.75 from both sides
y = -5.75
Add 32 + 14, 46.
subtract that from 54, 8.
