Giordano's Pizza Shop is famous for its spectacular Giordano's Giant, a large gourmet pizza that's big enough to feed 16 people! There is a base charge for the plain pizza, and then an additional charge per topping ordered from the list of 20 possible items. All the toppings are priced equally.


A Giordano's Giant pizza ordered with 2/5 of the possible toppings will cost $46.50. One with 30% of the possible toppings will cost $41.80. Using that information, answer the following questions:

Find an equation that expresses the total cost of a Giordano's Giant pizza in terms of the number of toppings ordered.

How much would a Giant pizza with all the possible toppings cost?

If a customer ordered a Giant pizza that cost $55.90, what percent of the toppings did she order?


i'm only an 8th grader , please help.

Okay this is my math extra credit and please no stupid answers like I don't want to do your homework or I will report you.
Okay 10 points to the best answer lets begin!
1)You have a bucket that holds 4 gallons or water and a second bucket the holds 7 gallon of water. The buckets have no markings. How can you go to the well and bring back exactly 5 gallons of water?
2)Okay this one involces a picture I will describe it best I can. It is a picture of 3 dots evenly placed out and a line under it and 3 foot steps under the line. Suppose you are a detective and found these tracks on some damp ground. Do you have any ideas how they were made?
3) Why are 1980 pennies worth almost 20$? (I don't think the answer is obvious as it look and maybe involves what the value of pennies in 1980 was.)
4) Another picture but very simple. 3 blank boxes plus another 3 blank boxes equal 3 blank boxes. Place the digits 1 through 9 in the nine squares to form a correct addition. Is there other ways todoit

If the line y = 4x + 3 is tangent to the curve y = x^2 + c, then c is...
A) 2
B) 4
C) 7
D) 11
E) 15
me and my friend got 7 and i think that's the right answer, but i don't really understand how i came to that conclusion. :/ can someone explain to me why it's C [7]?
and i do know tangent lines, so no need for any explanations about what a tangent line is. i just don't understand how c = 7 in the equation. :/
thanks!

Is it usually y=mx+c or y=mx+b?
I've seen people use both but which one are you supposed to use? Explain please.

An object has a top, side, and front view that all have a round outside border, a perfect circle of diameter = 1. What is the maximum volume this object can have?

I am talking about orthogonal views like you see in drafting.
