Answer:

[tex]\large \boxed{\text{A. 3.0 h}}[/tex]

Step-by-step explanation:

The bill          = $190

Less flat fee  =    25

Work done   = $165

[tex]\text{Hours worked} = \$165 \times \dfrac{\text{1 h}}{\$55} = \textbf{3.0 h}\\\\\text{The electrician was on the job for $\large \boxed{\textbf{3.0 h}}$}[/tex]
