A school principal ordered 100 pizzas for
a total of $1255. Cheese pizzas cost
$11.50 each, and pepperoni pizzas cost
$13.00 each. Which of the following
systems of linear equations can be used to
determine c, the number of cheese pizzas
the principal ordered, and p, the number
of pepperoni pizzas the principal ordered?
A. c+P = 100
13c + 11.50p = 1255
B. c-p= 100
13c + 11.50p = 1255
C. c+p= 100
11.50c + 13p = 1255
D. c-p=100
11.50c - 13p = 1255

c + p = 100

11.50c + 13p = 1255

Step-by-step explanation:

c = number of cheese pizzas

p = number of pepperoni pizza

If the school principal ordered 100 pizzas, then the equation would be...

c + p = 100

Since cheese pizzas cost $11.50 and pepperoni pizzas cost $13.00, then you would plug them into an equation where they equal to the total cost, $1255.

11.50c + 13p = 1255

So, your answer is letter choice C.

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
