Answer:
360x
Step-by-step explanation:
Given
Savings: x dollars, monthly
Duration: 30 years
Required
His savings after 30 years
To get his savings after 30 years,
- First we need to get his savings in a year.
- Then we multiply this result by 30
The reason why we need to get his yearly savings is because his savings was given on a monthly basis.
There are 12 months in a year;
Hence, his savings in a year is 12 * x
Savings = 12x in a year.
If his savings in a year is 12x dollas
His savings in 30 years will be
30 * 12x dollars
30 * 12x = 360x dollars
Hence, his savings after 30years is 360x
