Answer:
P = 0.5Q - 20
Step-by-step explanation:
P = kQ + c
substitute Q = 60 , P = 10 into the equation
10 = 60k + c → (1)
substitute Q = 240, P = 100 into the equation
100 = 240k + c → (2)
subtract (1) from (2) term by term to eliminate c
90 = 180k ( divide both sides by 180 )
= 
= 0.5 = k
substitute k = 0.5 into (1) and solve for c
10 = 60(0.5) + c
10 = 30 + c ( subtract 30 from both sides )
- 20 = c
then
P = 0.5Q - 20
8.75 x 37.5= ? Well all you do is have to line up the decimals and work it out! :) it's simple

Step-by-step explanation:
Answer:
4 / 9
Step-by-step explanation:
Solution:-
- Michael bus rental agency has a total of n = 18 buses.
- Out all the available buses he has r = 8 buses with AC in them.
- If we were to randomly select a bus from his agency what is the probability that the bus would have an AC:
P ( Bus with AC ) = Favorable Outcomes / Total outcomes
= Number of bus with AC / Total Buses
= r / n
= 8 / 18
= 4 / 9
