2. Wilton drives a taxicab. He charges $40 per hour. One passenger gave Wilton a tip of $30. He gave Wilton a total of $150. He is wondering how many total hours he drove the passenger.(a) Define the unknown in the scenario and assign it a letter or symbol.(b) Write an equation to represent the amount of money Wilton earned on the trip.

 The unknown is rather the question of how many hours the taxi drove. We can give it the symbol X.

Your equation would be: 40x + 30 = 150

(SOLVED):
40x +30(-30) = 150(-30)
40x= 120
40/40=120/40
x=3

*The driver drove the passenger for 3 total hours*

Hope this was helpful to you! Have a good one.
