Answer:
5.5 months
Explanation:
Let m be the number of months that pass.
We can write an equation to resemble this problem [ 100 + 50m = 45 + 60m ]
Steps to solve:
100 + 50m = 45 + 60m
~Subtract 100 to both sides
50m = -55 + 60m
Subtract 60m to both sides
-10m = -55
~Divide -10 to both sides
m = 5.5
Best of Luck!
