: One U.S. gallon is equivalent to 0.1337 ft3, 1 ft is equivalent to 0.3048 m, and 1000 L are equivalent to 1 m3. By using those definitions, determine the conversion factor between gallons and liters.

We have been given that on the day of his 18th birthday Harry decided to start saving money regularly . Starting on that day, he could save 30.00 on the same date every month. We are asked to find the amount saved by the day before Harry's 60th birthday.

First of all, we will find years from 18 years to 60 years.

We know that 1 year equals 12 months.

To find total amount saved, we will multiply 504 months by amount saved per month.

Therefore, Harry would have saved by the day before his 60th birthday.
