Answer:
6 hours
Step-by-step explanation:
Let the number of hours that Jane worked = x
Jane earns $10 per hour babysitting she also earned a one time fee of $40 she earns a total of $100
Using the straight line equation
y = mx + C
y = Total fees that she earned = $100
x = number of hours she worked = ??
C = One time fee = $40
m = Amount paid per hour = $10
Therefore,
$100 = $10 × x + $40
100 = 10x + 40
Subtract 40 from both sides
100 - 40= 10x + 40 - 40
60 = 10x
x = 60/10
x = 6 hours
The number of hours Jane worked to earn $100 total is 6 hours
