a) Menon has 992 stickers. We can find this by writing an algebraic expression for the number of stickers, with x being the number that Lindsay has. This gives us:
x + 4x = 1240
5x = 1240
x = 248
Now we multiply 248 by 4 to get 992.
b) There are 2 stickers left over. First we have to divide 992 by 6, which gives us 165 as a whole number, but then a remainder of 2. That means that there are two stickers left.
c) Menon needs 4 more stickers, as 6 - 2 = 4, and there are 6 stickers per page.
I hope this helps! Let me know if you have any questions :)
