Emma has $26 for her expenses. She spent $12.81, including tax, on a new book. , she needs to set aside $10.00 for a lunch outing next week. If stickers cost $0.42 per package, tax included, the number of packages (p) Emma can buy. 1 point
a. p less than or equal to 7
b. p greater than or equal to 7
To find the number of packages Emma can buy, we need to subtract the amount she spent on the book and the amount she needs to set aside for lunch from her total expenses: $26 - $12.81 - $10.00 = $3.19.
Since each package of stickers costs $0.42, we can divide the remaining amount by the cost per package: $3.19 / $0.42 = 7.59.
Since Emma cannot purchase a fraction of a package, she can buy a maximum of 7 packages.
Therefore, the answer is: a. p less than or equal to 7.
