The bill for repairing a car was $\$330$ . The cost for parts was $\$155$ . The cost for labor was $\$25$ per hour. How many hours did the repair work take?

A) $7$ hours
B) $14$ hours
C) $2$ $\text{ hours }$
D) $13$ hours
E) $9$ hours

The total bill was $330, and the cost for parts was $155. Subtracting the cost of parts from the total gives $330 - $155 = $175. Since labor costs $25 per hour, dividing the remaining amount by the hourly rate gives $175 / $25 = 7 hours.
