Solve using two equations with two variables.
The engineering club at MCTC ran a coffee and donut sale to raise money for the club's activities. The first week, they made a profit of $200. The second week, they sold three times as many donuts, but half the number of coffees, and made a profit of $225. If the profit for each donut was $0.50 and the profit for each coffee was $0.75, how many donuts and coffees did they sell the first week?
