Question

Arnold's company reimburses his expenses on food, lodging, and conveyance during business trips. The company pays $40 a day for food and lodging and $0.50 for each mile traveled. Arnold drove 400 miles and was reimbursed $2600.

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

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

Part C: How many days did Arnold spend on this trip?

Answer 1

40d + .50(400) = 2600 -- your equation

40d + 200 = 2600
40d = 2600 - 200 (subtraction equality)
40d = 2400
d = 2400/40 (division equality)
d = 60 -- He spent 60 days
