David's company reimburses his expenses on food, lodging, and conveyance during business trips. The company pays $60 a day for food and lodging and $0.65 for each mile traveled. David drove 600 miles and was reimbursed $3,390.

Part A: Create an equation that will determine the number of days x on the trip (3 points)

Each day for x days $60 is spent on food and lodgings, that is a total of 60x dollars

the company pays 65c for each of 600miles  that is .65*600=$390

so     390+60x = 3390

If I solve this equation I will have the number of days.   



Part B: Solve this equation justifying each step with an algebraic property of equality

390+60x = 3390    Subtract 390 from both sides

And you can finish it.
