enot [183]

Answer:

19 hours.

Step-by-step explanation:

T = -14 -76 + 19h

The -14 is the cost for tolls, and the -76 is the cost for gas. The 19h is the amount she'll get per hour if she makes $19/hour. And T is the total profit

We want to solve for h if T = 260

260 = -14 -76 + 19h

+14 +14

274 = -76 +19h

+76 +76

350 = 19h

/19 /19

18.42 = h

She must work 19 hours.

Hope this helps!
