Hey guys I need some help with this question PLZ:
A telecommunications company offers a rental deal which costs $30 per month plus 50c per call.
a) Find the total cost (T1) for making x calls in a given month
b)Find the total cost for making 52 calls in a given month
ANOTHER company charges $10 per month plus 80c per call.
c) Find the total cost (T2) for making x calls in a given month.
d) Find the total cost for making 52 calls in a given month.
e) If a potential customer averages 52 calls per month, which company should she buy the phone from?
THANK YOU SO MUCH to anyone who answers this question for me, it would be a big help.
30 + .50x = T1
Substitute 52 for x and solve.
Do a similar procedure for the other company.
Sure! I can help you with that. Let's go step by step to find the answers to each question.
a) To find the total cost (T1) for making x calls in a given month using the first company's rental deal, we need to add the monthly rental cost of $30 to the cost of each call. Since there is a charge of 50 cents per call, the formula would be:
T1 = $30 + ($0.50 * x)
b) To find the total cost for making 52 calls in a given month with the first company's rental deal, we can use the same formula from the previous question and substitute x with 52:
T1 = $30 + ($0.50 * 52)
c) To find the total cost (T2) for making x calls in a given month using the second company's rental deal, we need to add the monthly rental cost of $10 to the cost of each call. Since there is a charge of 80 cents per call, the formula would be:
T2 = $10 + ($0.80 * x)
d) To find the total cost for making 52 calls in a given month with the second company's rental deal, we can use the same formula from the previous question and substitute x with 52:
T2 = $10 + ($0.80 * 52)
e) If a potential customer averages 52 calls per month, we can calculate the total cost for each company using the formulas from the previous questions:
T1 = $30 + ($0.50 * 52)
T2 = $10 + ($0.80 * 52)
The customer should choose the company that offers the cheaper total cost, so you can compare T1 and T2 to determine the better option.
I hope this helps! Let me know if you have any other questions.
