The hourly wage is $20 per hour and working for 5 hours earns $100
Two variables are said to be proportional or have a proportional relationship when they have equivalent ratios. That is they increase or decrease by a factor.
Let y represent the total wage and let x represent the number of hours worked.
A) Since $100 is earned for 5 hours, hence:
Hourly wage = $100/5 hours
Hourly wage = $20 per hour
B) The linear relationship is given by:
y = 20x
C) Working for 5 hours gives:
y = 20(5)
y = $100
