Example Question #1 : How To Solve One Step Equations

Alegra is taking a cooking class with friends. It is 40 dollars for every two people who participate because people are supposed to work in pairs. But if someone does not have a partner, that person can still participate but must pay $30 for him or herself. Alegra's four best friends participate in the class with her, and they divide the cost evenly. What is the total cost per person?

Possible Answers:

60 dollars

30 dollars

22 dollars

20 dollars

Correct answer:

22 dollars

Explanation:

Since Alegra is taking the class with 4 friends, that means there are a total of 5 people. This means that there are 2 pairs of friends, and one alone friend. 

Below are the prices that will be charged based on this make up:

2 pairs of people at 40 dollars per pair = 80 dollars

1 solo person at 30 dollars per person = 30 dollars

80 dollars plus 30 dollars is 110 dollars, the grand total. 

When 110 dollars is divided by 5, the answer is 22. Therefore, 22 dollars is the correct answer.
