Respuesta :

Given:

Charge for each repair = $75

Additional charge per hour = $42

The expression is used to calculate the total charge, in dollars, for each repair appointment:

75 + 42h

Let h represent the number of hours Susna works during an appointment.

To find the total charge if Susan works for 6 hours, substitute 6 for h in the expression and evaluate.

Thus, we have:

h = 6

75 + 42h

75 + 42(6) = 75 + 252 = 327

Therefore, the total charge in dollars if Susan works for 6 hours is = $327

ANSWER:

$327
