Answer:
24 days
Step-by-step explanation:
Given that;
Brandon mows his lawn once every 4 days, Thomas mows his lawn once every 3 days. Celena mows her lawn once every 6 days. Then assuming today is day 1,
Brandon will mows his lawn on the following dates
1,5,9,13,17,21,25,29 (adding 4 days)
Thomas will mows his lawn on the following dates
1,4,7,10,13,16,19,22,25,28 (adding 3 days)
Celena will mows her lawn on the following dates
1,7,13,19,25,31 (adding 6 days)
Comparing all the days, all 3 will mow their lawns on the 25th which is 24 days after the first day.
