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 lunch outing next week. If stickers cost $0.42!per package, tax included, describe the maximum number of packages (p) Emma can buy.

Answer 1

Emma spent a total of $12.81 + $10.00 = $<<12.81+10=22.81>>22.81 on the book and lunch outing.
Emma has $26 - $22.81 = $<<26-22.81=3.19>>3.19 left for stickers.
The maximum number of packages Emma can buy is $3.19 / $0.42/package = <<3.19/0.42=7.595238095238095>>7.59 packages.
Since Emma cannot buy a fraction of a package, the maximum number of packages she can buy is 7. Answer: \boxed{7}.
