Megan is making food for a party. She has to spend 20 minutes preparing one dish in the oven. Each dish can feed 5 people. She spends 2 hours preparing as many of these dishes as she can for the party. How many people can she feed with these dishes? Give the rationale and then the answer.
Let's think step by step. First, we need to determine the total amount of minutes available for cooking. We do this by performing 2 * 60 = 120, as there are 60 minutes in an hour. Now that we know we have 120 minutes, we then divide the preparation time into the total amount of time by performing 120 / 20 = 6 dishes capable of being made. Since each dish can feed 5 people, we find the total number of people fed by performing 5 * 6 = 30 people.. The answer is: 30.

Sally sews 4 shirts on Monday, 3 shirts on Tuesday, and 2 shirts on Wednesday. Each shirt has 5 buttons. How many buttons does Sally need to sew all the shirts? Give the rationale and then the answer.
Let's think step by step. Total number of shirts Sally sews is 4 + 3 + 2 = 9 shirts. The total number of buttons she needs is 9 x 5 = 45 buttons.. The answer is: 45.

A bird watcher records the number of birds he sees each day. One Monday he sees 70 birds. On Tuesday he sees half as many birds as he did on Monday. On Wednesday he sees 8 more birds than he did on Tuesday. How many total birds did the bird watcher see from Monday to Wednesday? Give the rationale and then the answer.
Let's think step by step. Monday:70. Tuesday:70 / 2 = 35. Wednesday:35 + 8 = 43. Total:70 + 35 + 43 = 148 birds.. The answer is: 148.
