First, change everything into minutes.
12 noon is 12 by 60 which = 720 minutes.
9am is 9 by 12 which = 540 minutes.
X is now your number of minutes before noon.So noon - x is the next step:
720 - x
20 minutes ago it was 720 - x - 20
720 - x - 20= 540 + 3x (3x because you're looking for 3 times as many minutes)
720 - 20 - 540=4x (you combine all the like numbers and variables)
160 = 4x
160/4= x
40 = x
Your answer is 40 minutes

The answer is four months
Step-by-step explanation:
You have a starting cost of $50 with a $20 fee every month
OR
You have a starting cost of $30 with a $25 fee every month
Start: $50 ($20 per month)
M1 = $70, M2 = $90, M3 = $110, M4 = $130
Start: $30 ($25 per month)
M1 = $55, M2 = $80, M3 = $105, M4 = $130
In conclusion, the prices of the two will match at Month 4
