If call minutes cost 8 cents each and text messages cost 5 cents each and her bill was $34.26, how many minutes did she use? (Please state which system you are using)
Answers
Answer:
⇒Let the no. of call minute be = x
⇒& no. of text messages be = y
⇒As total number of minutes used and text messages sent last month was 561
So x + y = 561.................................(1)
⇒Now as call minutes cost 8 cents each and text messages cost 5 cents each and her bill was $34.26
So 8x + 5y = 3426............................(2)
On solving equation 1 & 2 we have
we got x = 354 cent
& y = 207 cent
Answer: Bella used 207 minutes in calling.
Given Bella's cell phone plan is for each call minute and text message she sends.
Last month the total number of minutes used and text messages were 561.
call minutes cost 8 cents and text messages cost 5 cents.
Now her bill was $34.26
the number of minutes she used is to be found.
Let the number of minutes be x,
the number of text messages be (561 - x),
According to the ques,
0.08x + 0.05(561 - x) = 34.26
28.05 + 0.03x = 34.26
0.03x = 6.21
x = 207
The number of minutes she used be, 207
To conclude in one sentence, she used 207 minutes in calling.
