A dormitory manager buys 38 bed sheets and 61 towels for $791.50. The manager get another 54 bed sheets and 50 towels for $923 f
-Dominant- [34]
38b + 61t = 791.50....multiply by 27
54b + 50t = 923.....multiply by -19
-------------------
1026b + 1647t = 21370.5 (result of multiplying by 27)
-1026b - 950t = - 17537 (result of multiplying by -19)
------------------add
697t = 3833.50
t = 3833.50 / 697
t = 5.50 <=== cost of each towel

38b + 61t = 791.50
38b + 61(5.50) = 791.50
38b + 335.50 = 791.50
38b = 791.50 - 335.50
38b = 456
b = 456/38
b = 12 <== cost of each bed sheet

so the cost of 1 towel and 1 bed sheet is : 12 + 5.50 = 17.50

Can someone please help me with this one question?
Scilla [17]
It's been awhile since I've worked with infinite series and partial sums, but here are my thoughts:
A. the first 4 terms:  -4, - \frac{4}{3}, -\frac{4}{9}, - \frac{4}{27}
B. In examining the partial sums of the series, it appears that the sequence produced has a limit and therefore the series would be convergent.
C. the limit or sum of the series looks to be -5    Below look at the sequence of partial sums:  
-4, -5 \frac{1}{3}, -5 \frac{7}{9}, -5 \frac{25}{27}

So you can see we're getting closer and closer to -5

Hey there! I'm happy to help!

We see that both Mr Ali and Mr Abid got at least 150,000. If you look over one more digit, Mr Abid has 8 and Mr Ali has 6, so Mr Abid has over 2,000 more votes.

Have a wonderful day! :D
