Answer:
Let number of laps she walked be equal to L
L=$7
7L = $105 (equation)
OPTIONAL: If you want to find how may laps she walked, divide both sides by 7
L = 105/7 = 15
She walked 15 laps

Step-by-step explanation:
Using linear function concepts, it is found that the representation of the value of 4,000 is given by:
B the gallons of water initially in the pool.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
In this problem, the amount of water in the pool after x hours is modeled by:
y = -720 x + 4000.
4000 is the y-intercept, which is the initial amount of water in the pool, hence option B is correct.
