Solution:
Given:
[tex]\frac{e}{240}\leq0.03[/tex]
Cross multiplying;
[tex]\begin{gathered} e\leq0.03\times240 \\ e\leq7.2 \end{gathered}[/tex]
Since computers are whole and not a part, the nearest whole number is 7.
This means 7 computers or less can be made in error and still be within the company's goal of no more than 3% error.
Therefore, the correct answer that will be within the company's goal of no more than 3% errors will be;
[tex]e\leq7[/tex]
