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
Answer:
Step-by-step explanation:
velocity of turtle = 5 feet / min
velocity of snail = - 11 feet / min
By using the formula of relative velcoity
the velocity of turtle with respect to snail is
V' = velocity of turtle - velocity of snail
V' = 5 - (- 11)
V' = 16 feet / min
