Answer:
$32.03
Step-by-step explanation:
Since there is a tax rate, you want to multiply $30.50 by 1.05 since you are adding tax to it and it is 5%. You should get 32.025 as the result, but since you need to round it, it is $32.03.
No it doesn’t.
it’s not a straight line at all.
Answer:
x=0
Step-by-step explanation:
The axis of symmetry: 
when the equation is 
The given equation is:
To make the a and b values more easily identifiable, we can rewrite it like this:
Now, we can tell that a=1 and b=0. Plug these into the equation :
Therefore, the equation for the axis of symmetry for the parabola is x=0.

Esecially the problem is 3x +x < 160
To find this out we first need to combine like terms
4x<160
Then get rid of the coefficient. In this problem, we divide by 4
x<40
So Rachel has to be less then 40, and Stephanie has to be less than 120.
Any questions?
