The image shows a word problem that reads:

"Betty sold 4 times as many oranges as apples. She sold a total of 60 apples and oranges. How many apples did Betty sell?"

### Solution:

Let's define the number of apples Betty sold as \( x \).

- According to the problem, the number of oranges she sold is 4 times the number of apples. So, the number of oranges is \( 4x \).
- The total number of apples and oranges sold is 60, which gives the equation:
  \[
  x + 4x = 60
  \]
  Simplifying this:
  \[
  5x = 60
  \]
  Dividing both sides by 5:
  \[
  x = 12
  \]

Thus, Betty sold **12 apples**.

Would you like a detailed explanation of how I solved this? Here are five questions related to this concept:

1. How would the equation change if Betty sold 3 times as many oranges as apples?
2. What if the total number of apples and oranges sold was 75? How many apples would Betty have sold then?
3. How can this method be applied to a similar problem where 2 types of items are sold at different ratios?
4. What are some other types of word problems involving ratios like this one?
5. How do systems of equations help solve word problems with more than two variables?

### Tip:
Always define variables for unknown quantities when solving word problems. This helps set up equations clearly and makes solving easier!
