I believe this is ur answer.
Answer:
$88.72 (89 dollars for a hat dude what a good deal. Finn officially fell for the trap. Watch episode 2 of Affording to buy a 100$ hat with Finn!)
Step-by-step explanation:
Step 1: Make an equation (98.58 x 90%)
Step 2: Solve (you can also do 98.58 x 0.9 to make it easier) and you get
$88.72
Hope this helps! :)

PS: Hopefully Finn doesn't have mental issues because he is buying a "cheap" hat.
<span>the train cannot exceed a length of 1100 feet
Now, train A = 28 cars at 30 feet each
Therefore, Train A's total length = 28*30 = 840 feet < 1100 feet.
</span>Now, train B = 22 cars at 40 feet each
Therefore, Train B's total length = 22*40 = 880 feet < 1100 feet.
Thus, both the <span>trains meet the requirement. </span>
