Answer:

  • 450 miles
  • $117.50

Step-by-step explanation:

The difference in fixed cost is $9; the difference in per-mile cost is $0.02. The difference in per-mile cost will equal the difference in fixed cost for a distance of ...

   $9.00/($0.02/mi) = 450 mi

At that distance, the rental cost is ...

  $50 +450×$0.15 = $50 +67.50 = $117.50

Both plans will cost $117.50 for 450 miles of driving.

Answer:

106 - 8h = 34

Whenever a math question says "when <em>h </em>= 9," they mean you substitute this number where <em>h </em>is in the equation.

106 - 8(9) = 34

106 - 72 = 34

34 = 34

This means the fact that h = 9 <u>is a solution for h.</u>

<em>I hope this helps! I would really appreciate it if you would please mark me brainliest! Have a blessed day!</em>
