Question: Frank is making hamburgers and he wants to sell them to make $50. Frank is selling each hamburger for $5 and 2 people purchased 4 and another 2 customers purchased 2 hamburgers. How many more hamburgers does Frank need to sell to make $50?
Answer with step-by-step thinking: Frank sold 4 hamburgers and then sold 2 more, so all together Frank already sold 4 + 2 = 6 hamburgers. If each hamburger is $5 and he sold 6 hamburgers already, Frank has made 5 * 6 = 30 dollars. Frank wants to make $50 and has already made $30, so Frank still needs 50 - 30 = 20 dollars. Since he needs $20 and each hamburger is $5, Frank needs to sell 20 / 5 = 4 more hamburgers.
So the answer is 4.


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.
Answer with step-by-step thinking: 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.
So the answer is 45.


Question: Katya sold 8 glasses of lemonade and Ricky sold 9 glasses of lemonade. If Tina sold twice as many as Katya and Ricky's combined sales, how many more glasses of lemonade than Katya did Tina sell?
Answer with step-by-step thinking:
Katya and Ricky sold 8 + 9 = 17 glasses of lemonade. Tina sold 17 x 2 = 34 glasses of lemonade. Tina sold 34 - 8 = 26 more glasses of lemonade than Katya.
So the answer is 26.
