Mary wants to spend $240 or moreon buying chocolate as presents for guests at her party. One pack costs $2, so, how many packs of chocalate she can buy?

Let x represent the number of packs of chocolate Mary can buy. According to all inforamtions, we get the following inequality:

\(\displaystyle{2}{x}\Rightarrow{240}\)

We need to divide both sides by 2 and get:

\(\displaystyle{2}\frac{{x}}{{2}}\Rightarrow\frac{{240}}{{2}}\)

\(\displaystyle{x}\Rightarrow{120}\)

So. she can at least buy 120 packs of chocolate or more.
