Jackson and Tyson both work at the same pizza restaurant after school. Jackson works every 3 days and Tyson works every 5 days. If they both work on the same day today, how many more days until they work together again?
The common multiple between 3 and 5 is 15.
Jackson works every 3 days, so in 15 days, he will work 15/3 = <<15/3=5>>5 times.
Tyson works every 5 days, so in 15 days, he will work 15/5 = <<15/5=3>>3 times.
Today is 1 out of those 5 days for Jackson and 1 out of those 3 days for Tyson.
So they won't work together again until 15 - 1 = <<15-1=14>>14 more days. Answer: \boxed{14}.
