Question

Your friend asks you to help him with his snow shoveling business and will pay you 3 pennies for the first job. You agree to help if he triples your payment for each job completed. After 2 shoveling jobs, you will receive 9 pennies, and after 3 shoveling jobs, you will receive 27 pennies. Complete and solve the equation that finds the number of pennies he will pay you after the seventh shoveling job.

Answer 1

First job = 3 pennies
Second job = 9 pennies 
Third job = 27 pennies 

Do you see the pattern? The pennies are being multiplied by 3 every job or tripling.

Fourth job = 81 pennies
Fifth job = 243 pennies
Sixth job = 729 pennies
Seventh job = 2,187

So the answer would be that after the seventh shoveling job you'd receive 2,187 pennies.
