Simple interest rate is the interest eared on principal amount only over time:

Hence, the interest earned is $94.50
#$770 at 4.19 for 3 years:

Hence, the interest earned is $96.79
<span>Divide 800 / 20 = 40,
There will be 40 winners per draw.
800 / 100 = 8, 1% will be 8 people in the draw.
40 / 8 = 5, 5% of winning, 95% of loosing.

This problem can be solved with a series of additions and subtractions.
The starting value is 500 and we first subtract 120 because on Monday they withdrew 120 dollars which leaves us with 380 dollars.
Next, we add 50 because on Wednesday they deposited 50 dollars which results in 430.
And, If I am not mistaken, we are done because when Braxton bought their basketball ticket, they used their debt card and did not withdrew from their checking account.
So, the answer is 430 dollars.
