First off, "whatever%" of "anything" is just (whatever/100) * anything
part A)
so... firm A got 11,000 invested, turned a profit of 24%, how much is 24% of 11000? well (24/100) * 11000
firm B got 14,000 invested, and returned 15% in profits, how much is 15% of 14000? (15/100) * 14000
part B)
for the amounts above, we get 2640 and 2100 respectively
so, the total profit "amount" is 2640 + 2100 or 4740
the total investement was 11000+14000 = 25000
if 25000 is the 100%, how much is 4740 in percentage?

solve for "x"
Answer: 14 miles ≤ D ≤ 22 miles.
Step-by-step explanation:
The mean distance traveled per gallon, is 18 miles.
But this can fluctuate, at most, by 4 miles.
Because we have here the "at most", we know that we should use the ≤, ≥ symbols.
Then, if the mean is 18mi, the range of possible distances traveled per gallon is:
(18 miles - 4 miles) ≤ D ≤ (18 miles + 4 miles)
Where D is the distance.
14 miles ≤ D ≤ 22 miles.
So the truck can get between 14 miles and 22 miles per gallon on the highway.
