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 [tex]65*600=$390[/tex]
= [tex]390+60x = 3390[/tex]
Part B: Solve this equation justifying each step with an algebraic property of equality
[tex]390+60x = 3390 [/tex]
Subtract 390 from both sides
[tex]60x=3390-390[/tex]
[tex]60x = 3000[/tex]
[tex]60x=3000/60[/tex]
[tex]x=50[/tex]
Part C = 50 days
