Question

Lisa has up to 7 1/2 hours to spend at an amusement park. She will spend 1 1/2 of those hours at the water park. She will spend x hours at each of the 3 other sections in the amusement park. Select the quantity that can be solved to determine the number of hours Lisa can spend in each of the other parks.

a. 7 1/2 - 1 1/2 - 3x
b. 7 1/2 - 1 1/2 - x
c. 7 1/2 - x
d. 1 1/2 - 3x

Answer 1

The quantity that can be solved to determine the number of hours Lisa can spend in each of the other parks is 7 1/2 - 1 1/2 - 3x, accounting for her total available time and the time spent at the water park and other sections.

Step-by-step explanation:

To determine the number of hours Lisa can spend in each of the other three sections at the amusement park, we need to set up an equation that accounts for her total available time and subtracts the time spent at the water park and in the other sections.

Since Lisa has 7 1/2 hours total and will spend 1 1/2 hours at the water park, we'll subtract that time. Then, because she will spend x hours in each of the three remaining sections, we multiply x by 3 to account for all three sections.

This gives us the equation 7 1/2 - 1 1/2 - 3x, representing the total time Lisa spends at all sections of the park, excluding the time already dedicated to the water park.
