Hank is raising money for the local homeless shelter. Hank makes $100 in a carwash and donates 90% of the proceeds to the local homeless shelter. Hank makes $80 in a bake sale and donates 75% of the proceeds to the local homeless shelter. Then he makes $50 mowing lawns and donates 100% of the proceeds to the local homeless shelter. How much money does Hank donate in total?
Thoughts? Step-by-step reasoning:
From the carwash, Hank donates $100 * 0.90 = $90. From the bake sale, Hank donates $80 * 0.75 = $60. From mowing lawns, Hank donates $50 * 1.00 = $50. Hank donates a total of $90 + $60 + $50 = $200.
Thus, the answer is 200.
