Answer:
17 hours
take $192 and divide it by 12 so you know how much they make per hour
$192 / 12 = 16
then you're going to take $272 and divide it by what you know now - how much they make per hour (this will get you how many hours they worked)
$272 / 16 = 17
I think that the answer is c
A negative slope means the line would be going downward, so you would go down first (instead of up as with a positive slope), then over right.
Therefore, you would go down 4 (or negative 4 considering you are going down) and right 1.
Rise over run still applies here. Rise over run is a fancy way of saying to put the number (or slope) in fraction form.
-4 as a fraction would be -4/1.
So start at (5,3), go down 4 and over 1, repeatedly and you got it.
**Just remember the rise over run can be confusing with negative slopes.**
Answer:
9 cents per day
Step-by-step explanation:
1 week = 7 days
Each razor lasts 1 week = 7 days
10 razors last 10 weeks = 10 * 7 days = 70 days
cost per day = (total cost)/(number of days)
cost per day = $6.30/(70 days) = $0.09/day
A, because you follow the numbers and just put "is to" and "as" in the middle.
