Answer:
T = $19.50 + $0.25(m - 200)
Step-by-step explanation:
Using the information provided we can create the following equation. This equation subtracts 200 from the total number of minutes and multiplies this by the cost per minute. Then it adds the fixed cost for the initial 200 minutes to get the total of the bill (T).
T = $19.50 + $0.25(m - 200)
Now that we have the equation we can plug-in you total for last month's bill and solve for m to calculate how many minutes you used last month.
$29.50 = $19.50 + $0.25(m - 200) ... distribute 0.25
$29.50 = $19.50 + $0.25m - 50 ... combine like terms
$29.50 = $0.25m - $30.5 ... add 30.5 on both sides
$60 = $0.25m ... divide both sides by 0.25
240 = m
Finally, we can see that you used a total of 240 minutes last month.
To find how much Fiona makes per hour divide her earnings (y) by the number of hours worked (x).
42/3= $14 per hour
Phillip makes $12 per hour.
14-12 = 2
Fiona makes $2 more per hour tan Phillip
Multiply both sides of the equation by 12
Answer:
$1.23
Step-by-step explanation:
To find how much they should charge, you have to find how much toilet paper they are selling compared to the bulk store. They are selling 6/72 or 1/12 of the rolls, meaning they should charge 1/12 the amount. To find this, simply divide 14.75 by 12, which is ~1.23$.
