The interval of time when Juan has more in savings than Fawzia is t > 4

How to determine the interval of time when Juan has more in savings than Fawzia.

From the question, we have:

Juan

Saving = $50

Additional = $20

So, the function is

J(t) = 50 + 20t

Fawzia

Saving = $90

Additional = $10

So, the function is

F(t) = 90 + 10t

Next, we plot the graphs of J(t) and F(t)

From the graph, the interval of time when Juan has more in savings than Fawzia is t > 4
