Question

Megan and four of her friends plan to go for a long drive. She buys 12 bottles of frappe and a few bottles of orange juice from a supermarket. The total number of bottles they have are four times that of orange juice bottles. How many bottles of orange juice did Megan buy?

Answer 1

Answer:

  4 bottles

Step-by-step explanation:

Let o represent the number orange juice bottles Megan bought. Then the total number of juice bottles is ...

  o + 12 = 4o

  12 = 3o . . . . . . . subtract o

  12/3 = o = 4 . . . . divide by the coefficient of o

Megan bought 4 bottles of orange juice.
