Equations that represents a linear function are Answers A and D
For this case we have that the cost of each pizza is given by the following function:
Where:
r: It's the radius of the pizza
IF a pizza cost $26.32 we have:
We cleared the radius, using :
We choose the positive value:
So, the radius of the pizza is
Then, the diameter is:
Finally, the diameter of the pizza is:

Answer:
Sarah spent 45.76
Jack spent 38.16
Jack spent more on tax
Step-by-step explanation:
Sarahs game costs:
tax = 44 *.04 = 1.76
Total cost = game + tax
= 44 + 1.76
=45.76
Jacks game costs:
tax = 36 *.06 = 2.16
Total cost = game + tax
= 36 + 2.16
=38.16
Jack spent more on tax
