Answer:
- c(m) = 39.95 +0.35m
- 85 minutes over 500
Step-by-step explanation:
Let m represent the number of minutes used over 500. Then the cost of the cell phone plan is ...
c(m) = 39.95 +0.35m
__
For a cost of 69.70, the number of excess minutes can be found by solving ...
69.70 = 39.95 +0.35m
29.75 = 0.35m . . . . . . . . . subtract 39.95
29.75/0.35 = m = 85 . . . . divide by the coefficient of m
The number of minutes of usage over 500 is 85.
This one is a little bit tricky and in order to solve this you need. To have a calculator with you
First you set up the equation (hopefully you remember the formula)
17500(1+r)^2=20475 (17500+2975)
Then you divide both side by 17500
You get (1+r)^2=1.17
And finally you solve this equation ( I assume that you know to to do it since you are in at least algebra 2 )
Then you get -10+3squareroot 13 all divided by 10 as the answer.
