To determine which expression correctly represents Olivia's total wages, we need to calculate her earnings for Friday and Saturday.
-
Calculate earnings for Friday: She charges $6.50 per hour and babysat for 3 hours, so: \[ 6.50 \times 3 = 19.50 \] This means she made $19.50 on Friday.
-
Calculate earnings for Saturday: Let's say she babysat for \( x \) hours on Saturday. Her earnings for Saturday would then be: \[ 6.50x \]
-
Total wages: To find the total wages for both days, we can add her earnings from Friday and Saturday: \[ 19.50 + 6.50x \]
Now, looking at the given options:
- A) \( 19.50 + 6.50x \)
- B) \( 6.50x + 3 \)
- C) \( 19.50 + 3x \)
- D) \( 3x + 6.50 \)
The correct expression that represents her total wages is:
A) \( 19.50 + 6.50x \).
