Answer:
187,244 dollars
Explanation:
In order to solve this problem we would need to make an equation that applies the 3.15% interest to the 3.6million investment, multiplies $4.25 by the 1,375 total transactions, and then adds all of the earnings together to calculate his total earnings for the year. To do so we first need to turn the percentage into a decimal format, we do this by dividing the percentage by 100.
3.15% / 100 = 0.0315
68,000 + (3,600,000 * 0.0315) + (4.25 * 1,375) = x
68,000 + 113,400 + 5,843.75 = x
187,243.75 = x
Finally, we can see that Darius made a total of 187,244 dollars (rounded up)
