Answer:

Step-by-step explanation:

Regular charge- $20                                      

Every hour of service cost- $40

Equation or slope intercept form-

C= 40h+20

Part 1-  20+40(8)=

40 multiplied by 8                320+20         = $340

Part 2-  20+40(10)=

40 multiplied by 10             400+20           = $420
