Answer:
672
Step-by-step explanation:
we multiply 28 by 24, as in each row there are 24 chairs, and there are 28 rows total
28 x 24 = 672
there were 672 chairs in total for graduation
<u>part b:</u>
we see that there are 672 chairs total for the graduation as shown in part a. we are then told that these 672 chairs were loaded into 4 trucks. to solve, we divide 672 by 4 to see how many chairs were in each truck:
672 / 4 = 168 < use long division to solve 672/4
It will take 7.925 years for the population to triple.
