On Monday, a restaurant sells forty dinners. On Tuesday, it sells 40 more dinners than it did Monday. On Wednesday, it sells half the amount of dinners it sold on Tuesday. On Thursday they changed their recipe, and then sold 3 more dinners than they did on Wednesday. How many dinners were sold in those 4 days? Let's be accurate as possible.
On Tuesday the restaurant sells 40 + 40 = 80 dinners. On Wednesday the restaurant sells 80 / 2 = 40 dinners. On Thursday the restaurant sells 40 + 3 = 43 dinners. In those 4 days, the restaurant sells a total of 40 + 80 + 40 + 43 = 203 dinners.
The answer: 203.
