Answer:
\(c(m) = 34.99+0.23m\)
Step-by-step explanation:
The slope-intercept form is given by:
\(y=mx+b\) where m is the slope and b is the y-intercept or initial value.
Here, c(m) represents the cost of bill c in terms of m and m represents the number of minutes.
As per the statement:
Bill bought a new cellular phone. his monthly bill will be $34.99 each month which includes 100 minutes of use.
⇒@@MATH_TOKEN_2@@
It is also given that additional minutes will cost $0.23 per minute.
⇒For additional minutes, he will cost per minute = $0.23
for m minutes, he will cost $0.23 m
Using the point slope intercept form we have;
\(c(m) = 34.99+0.23m\)
Therefore, an equation that represents the cost of the bill used above the 100 that are included in the base price is: \(c(m) =34.99+0.23m\)
