<span>In this question, we assume the pizza is a circle with radius r and diameter d. The radius is also known as (d/2). The area of a circle is A=pie*r^2. Q1: The area of a 16 inch pizza is A = pie * (16/2)^2 = pie * 8^2 = pie *64 = 201.06 in^2. Q2: To determine the cost per slice, just divide the total cost by the number of slices. In this case you would divide 12.50 by 8 (total slices) to get 12.50/8=$1.56/slice. Q3: The cost per square inch of the pizza would be total cost divided by the total area in square inches. This would give you 12.50/201.06 = $0.06 per square inch.</span>

Answer:
A
Step-by-step explanation:
44.99+299.49 = $344.38
$344.38 - store card ($75) = $269.48
422.76 - 269.48 - 2.5 = $150.78
Therefore answer is A
Answer:
One rose bush = $3
One bunch of ornamental grass = $4
Step-by-step explanation:
We can set up a system of equations to solve for this. Let cost of 1 rose bush be r and cost of 1 ornamental grass be g. Thus we can form 2 equations:
We can multiply the first equation by -2 so that we can eliminate g. Thus, we have:
Thus, 1 rose bush is $3. Now plugging in r = 3 into the first original equation, we can solve for g:
Thus, 1 bunch of ornamental grass is $4.
Answer:
Step-by-step explanation:
A.
R(x)=px=x(-45 x+1800)=-45 x²+1800 x
B.
C(x)=7000+100 x
C.
P(x)=R(x)-C(x)=-45 x²+1800 x-(7000+100 x)
or P(x)=-45x²+1800 x-100 x-7000
or P(x)=-45 x²+1700 x-7000
