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.

Answer:
you have a 50% chance of getting an odd number and a 60% chance of getting a number less than 26.
Step-by-step explanation:
Between 1 and 40 there are 20 odd numbers
20÷ 40 x 100=50, This means you have a 50% (20:20) chance of getting an odd number.
Between 1 and 40 there 25 numbers less than 26
15÷25 x 100=60, This means you have a 60% (25:15) chance of getting a number under 26.
