Answer:
spaghetti = 55
burger = 45
Step-by-step explanation:
spaghetti = x
burger = y
Jonathan's Bill = 2x + 3y = 245 (eq 1)
Judy's bill = 2x + 2y =200 (eq 2)
solving both equations 1 and 2
by subtraction
1y = 45
Substituting 1y = 45 in eq 2
2x + 2y = 200
2x + 2(45) =200
2x + 90 = 200
2x = 200 - 90
2× = 110
x = 110/2
x = 55
