An overseas Filipino workers in the Budget Department is Saudi Arabia. He found out that the cost C, in US dollars, of repairing a city street in that country was estimated using the function:

Question

C(m)=2,000+6,000m

where m is the number of miles of street to be repaired.

a. graph of the function for 0(less than or equal to)m(less than or equal to)10.

b.Estimate the cost of repairing 7 miles of a city street

c.How many miles of city street would have been repaired if the Budget Department had allotted $50,000?

THANK YOU :))

Answer 1

a) this is simply a straight line with y-intercept of 2000 and a slope of 6000
I would scale my graph so each vertical unit (the y) represents 1000 dollars, and each horizontal unit , the x's, represents the number of miles.

b) think in thousands only.
Can you mentally find 6x7 + 2 and then say "thousand" after it ?

c) solve:
2000 + 6000m = 50000

Answer 2

12

Answer 3

Draw the graph of the function for 0 ≤ m ≤ 10
