Answer:
the answer is c because it can be either greatly increased or decreased
Step-by-step explanation:
The question needs to be more specific. But assuming it is 0.5y/(4/9), I will solve it.
This would make it 4.5y/4 =y + 3/8
- Multiply 4 to both sides
4.5y = 4y + 12/8
- Subtract 4y to both sides
0.5y = 12/8
- Divide both sides by 0.5
y = 3
Now plug in to check.
0.5(3)/(4/9)=3+3/8
Both equals 3.375!

We have equation:
t=20x+31
x is number of years after 1997.
To calculate number of laptops in 2005:
x=2005-1997
x=8
t=20*8+31
t=160+31
t=191
In year 2005 school had 191 laptops.
