Given:
The percentage of customers who purchased gasoline is g = 12%.
The number of customers who purchased gasoline is n = 24.
The objective is to find a total number of customers altogether.
Explanation:
Consider the total number of customers altogether as x.
The value of x can be calculated as,
[tex]\begin{gathered} \frac{1\text{2 \%}}{100\text{ \%}}=\frac{24}{x} \\ x=\frac{100}{12}\times24 \\ x=200 \end{gathered}[/tex]Hence, the total number of customers altogether is 200.
