Question

What do you think we can do to figure out what the letter n represents? How many days do you think it will take to read 23 books? How did you figure that out?

Answer 1

First you turn 15% into a decimal, 15/10 = 0.15

Then you multiply 0.15 by 2860 to get 429.

$429 would be the commission for $2860.

Please let me know if you need further clarification.
