Jessica must plant 351 trees. In the past 6 days Jessica planted 234 trees. If she continues at this rate how many more days will it take her to plant all the trees
234 trees in 6 days so you divide 234 by 6 (39) so she plants 39 each day. Now you divide 351 by 39 (9) so at that rate it'll take 9 days in total and 6 days have already passed. So, 3more days.
