Answer:  a) the dependent variable is y, the amount he earns depending on x, the independent variable. x is the number of hours.

b) y = 5x + 10

c)  Bobby earns $27.50 for the 3.5 hour job

Step-by-step explanation: use the function y=5x + 10  substitute 3.5 for x

y = 5(3.5) + 10

y = 17.5 + 10

y= 27.5
