Emma has $26 for her weekend expenses. She spent $12.81, including tax, on a new book. Additionally, she needs to set aside $10.00 for a lunch outing next week. If stickers cost $0.42 per package, tax included, describe the maximum number of packages (p) Emma can buy.(1 point)

Emma has $26 - ($12.81 + $10.00) = $<<26-(12.81+10)=3.19>>3.19 remaining for stickers.

The cost of p packages of stickers, including tax, is $0.42p.
Therefore, the maximum number of packages Emma can buy is 3.19 / 0.42 = <<3.19/0.42=7.595238095238095>>7.6 packages.
Since Emma cannot buy a fraction of a package, she can buy a maximum of 7 packages. Answer: \boxed{7}.
