Worked Solution
Step 1 Add the first two prices: $3.60 + $0.75. Cents: 60 + 75 = 135¢ → write 35¢, carry $1. Dollars: 3 + 0 + 1 = $4. Result: $4.35.
Step 2 Add the third price: $4.35 + $0.55. Cents: 35 + 55 = 90¢. Dollars: 4 + 0 = $4. Result: $4.90.
Answer: The total cost is $4.90.
Correct answer: $4.90
