If the 30 students who ordered burgers were twice the number of students who ordered hot dogs, then 30 / 2 = 15 students ordered hot dogs. The total number of students is 15 + 30 = 45.
The answer: 45
Reverse engineering the question: After a trip, Mrs. Nalani took the students to the restaurant and told them they could order either a burger or a hot dog. If the number of students who ordered burgers was 30, twice the number of students who called for a hot dog, calculate the number of students at the restaurant.
Reasoning and answer: This past Saturday, Jessy and Alan told a total of 11 + 7 = 18 jokes together. Since Jessy told eleven jokes this past Saturday, when he doubles the number of jokes next Saturday, the number of jokes will be 2 * 11 = 22 next Saturday. At the same time, after telling seven jokes this Saturday, when he doubles the number of jokes next Saturday, Alan will tell 2 * 7 = 14 jokes. Next Saturday, they will tell 14 + 22 = 36 jokes together. In total, the number of jokes will be 36 + 18 = 54 jokes on the two Saturdays.
The answer: 54
What was the question?
Question: Jessy told eleven jokes this past Saturday, and Alan told seven jokes. If they doubled the number of jokes they told this past Saturday next Saturday, how many jokes would they have told in total together so far?
