Answer: A.
Step-by-step explanation:
Company A:
$200 + $2.99(30ft * 50ft) = $4,685
Company B:
30ft x 50 ft = 166.6667 sq yd.
$500 + $19.99(166.6667sq yd) = $3831.667
Company B is the better deal
AB is horizontal. The slope of a horizontal line is zero.
First, we subtract 1.75 from 7.60. This leaves us with 5.85 for miles. We divide 5.85 by 0.65 to get the number of miles she could travel. This gives us 9. So, Erika could travel 9 miles.
