Bridget needs an actor. Actor A is offering her services for an initial $250 in addition

Neporo4naja [7]

$\textit{Actor A charges 250 plus 50 per day}
\\ \quad \\

\begin{array}{llll}
days&charge
\\---&---\\
1&50\cdot 1\\
2&50\cdot 2\\
3&50\cdot 3\\
4&50\cdot 4\\
d&50\cdot x\implies 50d
\end{array}\quad meaning\implies A=250+50d$

$\textit{Actor B charges 2500 plus 60 per day}
\\ \quad \\
\begin{array}{llll}
days&charge
\\---&---\\
1&60\cdot 1\\
2&60\cdot 2\\
3&60\cdot 3\\
4&60\cdot 4\\
d&60\cdot x\implies 60d
\end{array}\quad meaning\implies B=200+60d
\\ \quad \\
when\ is A=B?\qquad well
\\ \quad \\

250+50d\quad =\quad 200+60d\impliedby \textit{solve for days "d"}$

An electric company charges a certain rate per kilowatt-hour (kWh) of electricity used and an administrative fee of $3.50. The c

Triss [41]

Answer:

Variable $r$ represents the slope of the equation.

Step-by-step explanation:

Given that the administrative fees that company charge is $3.50.

Also, the Zhao has a bill of $63.25.

The equation used by Zhao is

$63.25=r(800)+3.50$

We can compare the equation of a line in the slope-intercept form.

$y=mx+c$

We can see the y-intercept is $3.50 that is a fixed cost. And the company charged $63.25 that is the dependent variable.

Also, variable $r$ that is the rate per kilowatt-hour (kWh) represents the slope of the equation.
