Answer: Menon has 992 stickers 
Explanation:
Hi, to answer this question we have to write a system of equations with the information given: 
Lindsey and Menon have 1,240 stickers. 
M + L =1,240 (a) 
Where: 
- M = Menon's stickers 
 - L = Lindsey's stickers 
 
Menon has 4 times as many stickers as Lindsey. 
M = 4 L (b) 
Replacing the variable M on (a) by the value of M in (b). 
M + L =1,240 
(4L )+L = 1,240 
5L =1,240 
L = 1,240/5 
L= 248 
Replacing the value of L in (b) 
M = 4L 
M =4 (248) 
M = 992 
Menon has 992 stickers
