Let the number of fish sandwiches sold br represented by x
Then the number of grilled cheese sold is 2X
and the number of cheeseburgers 3(2x)
x + 2x + 3(2x) = 225
and solve
2)
Let x represent the no. of pounds of peanuts
Then x + 14 represents the no of pounds of the mixture

(2.25)x + (3.25)(14) = (2.65)(x + 14
and solve
