If every album is the same price, then let x = price for one album

jimthompson5910 (jim_thompson5910):

Then buying 5 albums, at x dollars a piece, totals in 5x dollars on the bill

jimthompson5910 (jim_thompson5910):

However, your limit is $30, so 5x = 30

jimthompson5910 (jim_thompson5910):

This is assuming you spend all $30

OpenStudy (hang254):

so the equation would be 5x=30?

jimthompson5910 (jim_thompson5910):

yes

OpenStudy (hang254):

how would i graph that?

jimthompson5910 (jim_thompson5910):

solve for x first

OpenStudy (hang254):

x=6

jimthompson5910 (jim_thompson5910):

Now draw a vertical line at x = 6

OpenStudy (hang254):

oh, ok. |dw:1347569122273:dw|

jimthompson5910 (jim_thompson5910):

yes you got it

OpenStudy (hang254):
