Answer:
.8
Step-by-step explanation:
4 and below rounds down
5 and up rounds up
.214=.2
.61=.6
.2+.6=.8
The quadratic formula is:
and
Let's identify our a, b, and c values:
a: -1
b: 1
c: 12
Plug in the values for a, b, and c into the equation. Let's do the first equation:
Simplify everything in the radical:
Simplify the radical:
Combine like terms:
Simplify:
This is one solution, now, let's solve for the other equation:
Since when simplified, everything is the same except the subtraction sign, we can skip the simplification again and change the sign to subtraction:
Combine like terms:
Simplify:
Your final answers are:
the x intercept is (12,0) and the y is (0,-8)
24*16.9=405.6
405.6/4.99=<span>0.812825651303
</span> which gives you $0.81 per bottle
You have to multiplicate this number by 2.
