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.
Let x be the number of pennies your friend will pay you after the seventh shoveling job.
If your payment triples for each job completed, then we can set up the following equation:
3 * 3 * 3 * 3 * 3 * 3 * 3 = x
Simplifying the equation, we have:
3^7 = x
Calculating 3^7, we find:
x = 2187
Therefore, your friend will pay you 2187 pennies after the seventh shoveling job.
