Asked by Sarah
When will Krystal and Desmond have the same amount of money in their accounts?

Never - their linear graphs would be parallel
After 3.5 hours, they will have the same amount
They will always have the same amount as their graphs are the same
After 5 hours, they will have the same amount

I don't have the equations or the graph, so I can't pick the correct choice yet. Give me the linear equations or the graph values for Krystal and Desmond and I'll solve it.
How to check yourself:
- If Krystal's amount is K(t) = a + b t and Desmond's is D(t) = c + d t, set a + b t = c + d t.
- If b ≠ d, solve t = (c − a)/(b − d). That gives the time they have the same amount.
- If b = d and a ≠ c, the lines are parallel → never.
- If b = d and a = c, the lines are identical → always.
If you paste the two equations (or the graph's intercepts/slopes), I'll calculate the exact answer.
