For his long distance phone service, joe pays a $3 monthly fee plus 11 cents per minute. Last month, joe's long distance bill was $17.96. For how many minutes was joe billed

136 minutes

Step-by-step explanation:

The amount that Joe pays is in two parts. He pays a definite amount for the month plus the amount per minute charge.

Thus,

Joe's monthly fee = $3 + $0.11n

where n is the number of minutes.

Joe's bill for the month = $17.96

So that,

$17.96 = $3 + $0.11n

$17.96 - $3 = $0.11

14.96 = $0.11n

n =

  = 136

The number of minutes that Joe was billed is 136.

In this case, Joe was billed for 136 minutes for the month.

it has the same slope and a different y-intercept

hope this : )

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
