D: none of the above
just in case, the answer is 26 miles, and you need to use the Pythagorean theorem
60 whatever unit it needs.
The correct answer is 66.
Answer: They must sell 116 more boxes to raise $270.
Solution:
For every box they sell, they get $1.35 profit.
They have sold 84 boxes already, then they have:
$1.35 * 84 = $113.40
They need $270, then they have to sell:
$270-$113.40=$156.60
For every box they sell, they get $1.35 profit, then they need to sell:
$156.60/$1.35=116 more boxes
Check:
116*$1.35=$156.60
84*$1.35=$113.40
$156.60+$113.40=$270.00
X = -8.5
set 2x + 17 = to 0
subtract 17 from both sides
divide by 2
