Edward deposited $5,500 into a savings account 5 years ago. The simple interest rate is 5%. How much money did Edward earn in interest? I really need help♡︎!

$1375 in interest and $6875 total.

Step-by-step explanation:

First you take the 84 people on the train and subtract it by 43 getting the answer of 41. Since 61 people entered the train after 43 got off, you add 61 + 41 to get 102. Lastly, you then subtract 22 from 102 to get 80.

Therefore, there are 80 people left on the train.
