Let's solve this step by step. Step 1: Determine the value of the drink From the first equation: Drink + Drink + Drink = 30 Since there are three drinks, we divide: Each drink = 10 Step 2: Determine the value of the burger From the second equation: Drink + Burger + Burger = 20 Substituting Drink = 10 10 + Burger + Burger = 20 So, Burger + Burger = 10 Dividing by 2: Each Burger = 5 Step 3: Determine the value of the fries From the third equation: Burger + Fries + Fries = 9 Substituting Burger = 5 5 + Fries + Fries = 9 So, Fries + Fries = 4 Dividing by 2: Each Fries = 2 Step 4: Solve the final equation The final equation is: Burger + (Fries × Drink) = ? Substituting values: 5 + (2 × 10) = 5 + 20 = 25 Answer: The final answer is 25.
