Using proportions, it is found that the complete sentence is:

"So I helped 54 customers in 7.5 hours yesterday."

  • This question is solved by proportions, using a rule of three.
  • In half an hour, 3.6 customers were helped. Hence, how many were helped in 7.5 hours?

The rule of three is:

0.5 hours - 3.6 customers

7.5 hours - x customers

Applying cross multiplication:

[tex]0.5x = 7.5(3.6)[/tex]

[tex]x = \frac{7.5(3.6)}{0.5}[/tex]

[tex]x = 54[/tex]

54 customers were helped.
