Answer: $2.58
Step-by-step explanation: You have 35 dog collars and you want to make 90 dollars. To figure out the minimum price for each collar to make your intended 90 dollar profit, you need to divide 90 by 35 and you get $2.58. That is an odd price, but it would get you your intended amount of money. I would recommend selling them for 3 dollars so you wont have to carry around change.

Kilo
Hecto
Deka
UNIT
Deci
Centi
Mili
Since we are converting milligrams into kilograms.
We have to divide by 6 spaces.
856 ÷
=> 0.000856
5x2=−30x−65
Subtract -30x-65 from both sides.
5x2−(−30x−65)=−30x−65−(−30x−65)
5x2+30x+65=0
Use quadratic formula with a=5, b=30, c=65.
x = −30±√−400 / 10
No solution.
