Answer:
21 units
Step-by-step explanation:
7 units in 5 hours means 14 units in 10 hours which means 21 units in 15 hours.
5x3=15
7x3=21
<span>First we add 2m to both sides, leaving 7m + 72 = 52 (since -2m + 2m cancels out). Next, we subtract 72 from both sides, bringing us to 7m = -20. Solving for m, we get -20/7. Since this is not one of the listed options, it is possible that the original poster has made a typographical error.</span>
