Tax = $55 * 9% = $55 * 0.09 = $4.95
Tip = $55 * 18% = $55 * 0.18 = $9.90
Total = $55 + $4.95 + $9.90 = $69.85</span><span>

Answer:
B. Y=4x+250
Step-by-step explanation:
Y= total cost for Paula's bakery per week
Cost of rent and electricity=$250
Ingredients for 1 cake =$4
Number of cake=x
Cost of x cake=$4*x
=$4x
Total cost (Y)=cost of rent and electricity+cost of making x cake
Y=$250+$4x
It can also be written as
Y=4x+250
The second one.
First of all, all the options involving zero make no sense, since it is not present in the inequality.
Then, the number line has a direction, which is rightwards. This means that the numbers get bigger and bigger as you walk the line to the right.
So, if
, it means that
is located to the right of

Answers may vary depending on the person reading the graph.
It is hard to tell what they think crosses nicely.
For example, I decided that the graph crossed nicely at the following points:



Step-by-step explanation:
I see that the graph crosses at
,
, and
.
The equation
tells us the
-intercept is
since when
we have
.
The
-intercept for our graph is
. Therefore,
.
So far we have the equation:
.
Let's enter the other points creating a system of linear equations to solve:


Let's simplify:


Let's subtract 3 on both sides:


I choose to solve the system by elimination.
Let's multiply the top equation by -3:


Now adding the equations results in:

Divide both sides by 24:

Now using one of the equations we can find
:
with 


Add 13/6 on both sides:



Divide both sides by 2:


So we have the equation:

Let's evaluate
now:
