Asked by Rani

Used books are being sold at $5 and used videos are being sold at $6. There are 175 total items sold and a total of $910 collected. How many videos were sold?
Answered by Rani
Okay, I have figured this out.


Total Items $$ Total
Books 175-v 5 5(175-v)
Videos v 6 6v
Total 175 --- $910

5(175-v) + 6v = 910

875- 5v + 6v = 910

1v (or just v) = 910-875

v = 35, or 35 videos

35 videos at $6 each = $200 sold

$910-200 = $710 left for books

$710/$5 (books) = 142 books sold

Sorry the "Total Items $$ Total" was supposed to be 3 columns.
Answered by Reiny
your number of books is not correct
should be 175-35 = 140

so 35 videos and 140 books

check: 35(6) + 140(5) = 910

35*6 is 210 not 200.
