Approximately 2 months

Step-by-step explanation:

Tricia: f (d) = 5.15m + 10.25

Melanie: f (d) = 10.25m

f (d) is the total savings altogether

m is the amount of months

5.15 (2) + 10.25 = 20.55

10.25 (2) = 20.50

They will have the same amount of savings in approximately 2 months

1.990291 is the actual time (in months) they will be the same
