Answer: She wins $20.19 per hour.
Step-by-step explanation:
Here we have two points of data.
in 12 hours of work, she had $525.40
in 25 hours of work, she had $788.00
If we want to see how much she gets paid per hour, we need to find the slope of the linear equation, we can do this by the next equation
s = (Y2 - Y1)/(X2 - X1) where Y2 = f(X2) and Y1 = f(X1) for a linear function f.
In this case, we have:
s = ($788 - $525.50)/(25 - 12) = $20.19
So she wins $20.19 dollars per hour, the initial savings is bigger than 12*$20.19 because she may have previous savings, from before she started this new work.
Given that Lily is working to save and buy a car, and the cost of the car is $3,000
Given data
After working for 12 hours Savings = $525.40
After working for 25 hours Savings = $788.00
To solve for her hourly pay, let us use the second data, which is "working for 25 hours Savings = $788.00"
Hence the hourly pay = total-savings/number of hours
Hourly pay =788.00/25
Hourly pay = $31.52 per hour
After the computation, we found from the above that her hourly pay is $31.52 per hour
