The percentage of Abigail's $2,325.00 monthly retirement income she has saved each month is 20%
What is the total savings for the nine months?
The fact that $627.75 saved for entertainment is only 15% of total savings means that we can determine the total savings in the period of nine months as shown below:
15%=$627.75
divide both sides by 15 to determine 1% of total savings
15%/15=$627.75/15
1%=$41.85
100%=$41.85*100
100% savings=$4,185.00
Now the total savings were saved over the period of 9 months, hence, monthly savings is determined as total savings divided by the number of months savings lasted
monthly savings=$4,185.00 /9
monthly savings=$465.00
monthly savings a percentage of monthly retirement income=$465.00/$2,325.00
monthly savings a percentage of monthly retirement income=20%
