A new shopping mall records 120 total shoppers on their first day of business.

Each day after that, the number of shoppers is 10% more than the number of shoppers the day before.

What is the total number of shoppers that visited the mall in the first 7 days?

Round your final answer to the nearest integer.

I know I could just dumbly math it out, but is there a better way?

Could somebody give me a hint?

Thank you!!!
