ALGEBRA 2: Aden buys 15 collectible coins per month. Caliana sells 5 coins from her collection of 100 each month. When will Aden have more coins than Caliana? Show your work.

Question

Kotesh · Answer

Let's say months = x when Aden will have same coins as Caliana.
Then 
15×x = 100 - 5×x
So x=5
After five months , 
Aden coins count 75
And Caliana coins  count 75.
So after six months Aden will have more coins than Caliana.

is that how to do the correct way in algebra 2 though?

bryanferia · Answer

The number of months it will take for Aden to have more coins than Caliana is greater than 5 months

How to write and solve equation?
Aden:

Number of coins bought per month = 15
Caliana:

Number of coins sold from her collection = 5
let

x = number of months

Aden = Caliana

15x > 100 - 5x

collect like terms

15x + 5x > 100

20x > 100

x > 100/20

x > 5 months
