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)Part B: Solve this equation justifying each step with an algebraic property of equality. (6 points)Part C: How many days did David spend on this trip? (1 points)

Respuesta :

For Part B, Part A of the equation is needed.
Each day for x ($60 food and lodgings).
Miles for y (600 miles)
3390=60x+0.65y
3390=60x+.65(600)
Equation: 3390=60x+390
Subtract 390 from both sides.
3000=60x
Divide 60 on both sides.
50=x

3390=60x+390
3390=60(50)+390
3390=3000+390
3390=3390
