Step-by-step explanation:
let the cost of apple pie be
and the cost of chocolate pie be
.
We then express the situation as:

#Make y the subject of the formula in equation 1 then substitute in 2:

Hence, the cost of a chocolate pie is $3
I think that the answer is A
Answer:
a= 1
b= -1
c= 3
Step-by-step explanation:
''a'' and "b" are the coefficients of x^2 and x respectively, where "c" is the constant number.
When solving a quadratic equation all the variables and constants should be on one side, in this case: x^2 -x +3=0.
Here the coefficient of x^2 is one, of x is -1 and constant is 3.
