Siti and Xinyi had the same number of stickers. After Siti gave away 55 stickers
and Xinyi threw away 15 stickers, Xinyi had three times as many stickers as Siti.
How many stickers did Xinyi have in the end?

Respuesta :

melancholy1644

Answer: 60 stickers

Step-by-step explanation:

Let's say Siti is s and Xinyi is x.

3(s - 55) = x - 15

And since s = x, we can just say that 3s - 165 = s - 15

2s = 150

s = 75

So, now Xinyi has 75 - 15 = 60 stickers.
