Answer:
Around 0.22
<u>FIRST THOUGH, I FEEL LIKE 90 MIGHT HAVE MEANT TO BEEN 0.9, SO IF SO SUBSTITUTE THE 90 BELOW FOR 0.9!</u>
<u></u>
Step-by-step explanation:
Okay, so first.
Company A will be 50 a day plus 0.4 a mile
Company B will be 30 a day plus 90 per mile
We can write an equation like this:
50 + 0.4m = 30 + 90m
m = miles they are the same
Then we solve for m.
50 + 0.4m = 30 + 90m
- 0.4m - 0.4m
50 = 30 + 89.6m
- 30 - 30
20 = 89.6m
Divide both sides by 89.6
Around 0.22!
Number 15 is 80 i dont know about the others...sorry
Since the point satisfies the equation
y = x +3
