We will just do the following steps:-
389 - 40 = 349
349 - 30 = 319
So, in the end your class had 319 milk jugs left.
Hope I helped ya!!
Let's say there were "x" in 1996, therefore, "x" is the 100%.
10 years later, there are 12440, and that is 1126% "more" than "x", since "x" is 100%, 1126% more than that is 100% + 1126%, or 1226%.
so, 12440 is really 1226% of whatever "x" happened to have been back then in 1996.
now, since we know that 12440 is 1226%, what is "x" then?
The area of a rectangle can be directly calculated using
the formula:
A = l * w
Where l is the length or the depth while w is the width
Therefore,
A = 50 feet * 100 feet
<span>A = 5000 square feet</span>
