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.
