a) Yes they are the correct simultaneous equations.

b) Yes you have each equation in the form y = ...
But have you graphed them to find the solution like the question asked??
Also, have you answered the question as written ie "How many calories are the pumpkin and raisin cookies?" x=247.5 needs to be interpreted as "The pumpkin cookies have .... calories".

c) You have solved the system simultaneously. You can check your own solution for x and y by substituting these values back into the original 2 equations. Question c) also asks you to solve using the elimination method. You don't seem to have done that.
