Hi, I would like a little help setting this math word problem up.?

Question

A call to Town A from a pay phone in Town B costs 83¢ for the first minute and 26¢ for each additional minute or portion of a minute. If a student has $6.80 in change, how long can she talk? I keep getting the wrong answer so I figured I wasn't putting it in the correct format. Thanks.

Answer 1

The problem is solved this way

0.83 + 0.26 n=6.8   here n min she is going to talk

n=22.96

because of the fact that she cannot talk part of the minute the answer is 22

Let's check

0.83 + 0.26*22= 6.55 (OK)

if he over-talks one more minute it will cost him  +0.26=6.81  (not OK)

Answer: 22 minutes

Answer 2

23 mins

Answer 3

It would be 6.8-.83/.26

Answer 4

It's a proportion. You can just subtract the first charged minute from the money amount first:

6.80- .83= 5.97

5.97/ X minutes= .26/ 1 minute

Cross multiply:

.26X= 5.97

Divide by the variable:

They have enough money to talk for 22.96 minutes

Break that down:

23 minutes and 36 seconds

Answer 5

Lex x be the call of the first minute, and y be the additional minutes.

you know the total cost of the call is $6.80

The first minute costs $0.83

the second min after costs $0.26

since  total charge is $6.80... and since the first minute costs $0.83, we know that after the first minute, he still has $5.97 left.

now just divided $5.97 by $0.26 =22.9615...

this means there's 22 minutes of talk time with $0.26/min

so he had the 1st minute + 22 minutes = 23 minutes

Answer 6

= ([$6.80 - $0.83]/$0.26) + 1

= ($5.97/$0.26) + 1

= 597/26 + 1

= 22 25/26 + 1

= 23 25/26

Answer: 23 25/26 min OR 23 min 57 9/13 seconds

Answer 7

1+ (5.97/.26) = minutes

Answer 8

$6.80 - 83¢ = $5.97   →  1 minute

($5.97)/26¢ = →  22.961538461538461538461538461538 minutes

22.961538461538461538461538461538 minutes + 1 minute

23.961538461538461538461538461538 minutes →   answer

Answer 9

I think if you set it up as y=.26x+.83, you can solve from there. just put $6.80 in for y and solve.

Answer 10

:)

does that help???

Answer 11

I think for about 8.somthing minutes

Answer 12

Let X=minutes after first minute

change every thing to cents

83+26X=680

26X=680-83

26X=597

X=22.96=23

she can talk =1+23= 24 minute

Answer 13

First subtract 6.80-.83= 5.97 now you need to find how many times 26 goes into 5.97 by division.
