Answer:
First company offers cheaper plane rate
Step-by-step explanation:
First company:
Phone Plans Plus telecommunications offers a plan of $20 per month for an unlimited calling and data plan and 10 cents per text message sent
so,
fixed rental plan for unlimited calling is $20 per month
message rate is $0.10 per texts
Second phone company:
TalkMore, a competing company, offers a plan of $55.00 per month for an identical unlimited calling and data plan and five cents per text message
fixed rental plan for unlimited calling is $55 per month
message rate is $0.10 per texts
We can see that message rates are same for both
But unlimited calling rate is different
So, $20 per month rate is cheaper than $55 per month
So,
First company offers cheaper plane rate
Answer:
Step-by-step explanation:
First company offers a plan of $20 per month for unlimited calling and data plan plus 10 cents per text message.
Second company offers a plan of $55 per month for unlimited calling and data plan plus 5 cents per text message.
Let the messages to be done in a month = x
therefore, charges for a month = 0.10x
for plan B cost of x messages in a month will be = 0.05x
so, monthly charges for plan A with x messages = 20 + 0.10x
similarly for plan B charges = 55 + 0.05x
Both the plans will be same when
20 + 0.10x = 55 + 0.05x
0.10x - 0.05x = 55 - 20
0.05x = 35
x = [tex]\frac{35}{0.05}[/tex] = 700
For 700 messages both the plans will cost the same.
Below 700 messages (600 messages) we have to pay for plan A = 20 + 0.10×600 = 20 + 60 = $80
And For plan B charges = 55 + 0.05×(600) = 55 + 30
= $85
This reveals that below 700 messages Plan A will be cheaper than Plan B but above 700 messages Plan B will Be economical.
