Not asking, but these kind of questions are hard, and you might want to exercise your brain with this problem.
Lina spent 1/5 of her money on 8 pencils and 2 markers. The cost of each marker is twice the cost of each pencil. She bought some more markers with 5/8 of her remaining money. How many markers did Lina buy altogether?

How much money did she have originally?
m = 2p
8p+2m = 8p+4p = 12p
since 12 pencils cost 1/5 of her money,
5/8 of the remaining 4/5 = 1/2 of the money
so, she bought another 30 pencils, making 38 in all
8p+2m = 8p+4p = 12p
since 12 pencils cost 1/5 of her money,
5/8 of the remaining 4/5 = 1/2 of the money
so, she bought another 30 pencils, making 38 in all
