A truck can be rented from company A for $130 a day plus $0.20 per mile. Company B charges $50 a day plus $0.60 per mile to rent
grin007 [14]

Answer:

200 miles

Step-by-step explanation:

<u>Company A</u>

  • Daily charge = $130
  • Per mile = $0.20
  • x miles per day = 130 + 0.2x

<u>Company B</u>

  • Daily charge = $50
  • Per mile = $0.60
  • x miles per day = 50 + 0.6x

<u>Assume x miles that makes same amount for both options, then:</u>

  • 130 + 0.2x = 50 + 0.6x
  • 0.6x - 0.2x = 130 - 50
  • 0.4x = 80
  • x = 80/0.4
  • x = 200 miles

EASY MATH QUESTION FREE POINYS
Yakvenalex [24]

Answer: x = 17

Step-by-step explanation:

2+x = 2x-15

subtract x on both sides

2 = x -15

add 15 to both sides

17 = x

------------------

17+2 = 2(17)-15

19 = 34 -15

19 = 19
