Marcella can wrap 15 packages using [tex]2\dfrac{1}{2}[/tex] roles.

Given information:

For every 3 packages that Marcella wraps, she uses 1/2 of a roll of wrapping paper.

So, 1 role can be utilized to wrap 6 packages.

Now, she is using [tex]2\dfrac{1}{2}[/tex] roles. It is required to find the number of packages that can be wrapped.

So, the number of packages that are wrapped using [tex]2\dfrac{1}{2}[/tex] roles will be calculated as,

[tex]6\times2\dfrac{1}{2}=6\times \dfrac{5}{2}\\=3\times 5\\=15\rm\; packages[/tex]

Therefore, she can wrap 15 packages using [tex]2\dfrac{1}{2}[/tex] roles.
