Allegra has a cell-phone plan that charges $65 per month and $0.10 for every minute that she uses the phone beyond what her plan allows. One month, she was billed $73.40.a. Define a variable for the unknown.
b. Write an equation to model the problem. Explain your answer.
c. Solve the equation. Show your work.
d. Find the number of minutes that Allegra went over the time that the plan allows. Explain your answer.
Please help me with this problem, I don’t understand it. Thanks in advance! :D

a. The unknown is how many minutes she used beyond the plan. So, we'll use "m" for the variable, to represent minutes.
b. 73.40 = 65 + 0.10m
The 73.40 is the total, which is why it's by itself. 65 represents the price per month for the plan, and 0.10m is the price per extra minute multiplied by the unknown amount of minutes used.
c. 73.40 = 65 + 0.10m
8.40 = 0.10m
84 = m
d. The number of minutes that Allegra went over the time that the plan allows is found by solving the equation we just wrote and solved. $0.10 is paid for every minute past the plan's allowance, meaning that "m" in the equation, when solved, shows us exactly how many minutes over Allegra went.

Beth = £130.
Let the money Adam gives Beth be x.
So Adam would have 500 -x.
Beth would then have 130 + x.
Adam now has twice as much as Beth.
500 - x = 2*(130 + x)
500 - x = 2*130 + 2*x
500 - x = 260 + 2x
- x - 2x = 260 - 500
-3x = - 240
x = -240/-3
x = 80
So Adam gave £80 to Beth.
To find the %: (80 / 500) * 100%. Use your calculator.
= 16 %.
So Adam gave away 16% of his money to Beth.

It says that 'y' is everything less than x-5 .
When x=0, the origin is at y=0, but the limit of the inequality is way down at -5.
False.
