Answer: putting it into a chart, when Calinana has 75, Aden will have 90
Step-by-step explanation:
Aden will have more coins than Caliana when x > 5
In Mathematics, the relationship between two values that are not equal is defined by inequalities. Inequality means not equal.
According to the given problem,
Let x = the number of months
If Aden buys 15 coins per month, he will have 15*x coins
Caliana starts with 100 coins, and sells 5 per month, so she has 100 - 5x coins
Aden has more coins than Caliana when 15x > 100 - 5x
Solving for x,
15x > 100 - 5x
⇒ 15x + 5x > 100
⇒ 20x > 100
⇒ x > 5
Hence, we can conclude that when when the number of months (x) is greater than 5, Aden will have more coins than Caliana.
