Because t is the number of weeks, replace t with 6 in the equation and solve for s.
s = -0.25(6) +4
s = -1.5 +4
s = 2.5
Now replace t with multiples of 6, use 12 and 18:
s =-.25(12) +4 = 1
s-0.25(18) +4 = -0.5
now fins the difference between the time frames:
2.5 - 1 = 1.5
1 - 0.5 = 1.5
The ice melts 1.5 meters every 6 weeks.
The problem deals with a division and the rest of it, that is dividing the total amount of pencils into 9 classrooms and the rest, lets express it as fraction:
935/9 = 103 + 8/9
that is, if we multiply 103*9 we get 927 and are 8 pencils left over, therefore, 8 pencils are donated to the library and each classroom gets 103 pencils, in total 935 pencils are donated.
