Ok, I have two telephone companies, one is offering calls at £0.10p with a monthly fee of £10, the second company is offering calls at £0.20p with a monthly fee of £5.
I am asked to create a formula using simultaneous equations, the question does not ask me to solve the equations.
I was told to use the letter "p" for the cost of calls per month, and "n" for the number of phone calls per month.
What I have learned so far is that the number of phone calls per month is not given, but the price per call and a monthly fee are, so based on this information I came up with the following formula.
N = 10p + 0.10
N = 5p + 0.20
Do these equations seem realistic, my understanding is that N would tell me the number of calls per month, and P would tell the total cost of calls per month.
or should the equations be;
N = 10 + 0.10p
N = 05 + 0.20p
