A music website sold 94 single songs and 67 albums today. The number of single downloads has been increasing by 22 each day. The number of album downloads has been decreasing by 5 each day. If these trends continue, in how many days will the number of single downloads by ten times the number of album downloads? Write and solve an equation to find the number of days. (Hint: choose a variable to represent the number of days.)
For extra credit, post your answer and explanation to the blog.

94+(22*y)=x
y=8 x=270
67-(5*y)=x
y=8 x=27
270/27=10 times as many single downloads.
It will take 8 days to get 10 times as many single downloads as album downloads.
