Question

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

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

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

Answer 2

First you need to make an equation.

let x represent the amount of days

60x+

$0.65 for each mile traveled, 600 miles traveled

600 times 0.65=390

60x+390=3390

Answer 3

that is for part a

Answer 4

for b and c just solve x<<the amount of days

Answer 5

questions?

Answer 6

hold on I'm trying to figure out b & c xd

Answer 7

whats after 60 x + ?? and is the final equation 60x+390=3390

Answer 8

yes ^

Answer 9

so to find x i subtract 3390-390= 3000 60x=3000 then 3000/60 and x=50??

Answer 10

yes :)

Answer 11

and how do i justify it with an algebraic property of equality

Answer 12

60x+390=3390

when you subtract your 390 to both sides.

it is the subtraction property of equality

Answer 13

like if 5=5

you subtract 2 on both sides. it will both equal 3..
subtraction property equality

Answer 14

how do i subtract from both sides? thats what I'm confused on a lot in math is the subtracting from both sides because don't i just need to subtract from one side?

Answer 15

you did it yourself lol look
60x+390=3390

you minus 390 on both sides theoretically

60x+390=3390
-390 -390

60x=3000
