Final answer:
To determine the cost of 2 bags of chips when 3 bags cost $5.55, calculate the unit price ($1.85) and then multiply by 2 to get the total ($3.70).
Step-by-step explanation:
To find out how much 2 bags of chips cost if 3 bags cost $5.55, we need to calculate the price per bag and then multiply that by 2. First, we divide $5.55 by 3 to find the price per bag: Price per bag = $5.55 ÷ 3 = $1.85
Then, we multiply the price per bag by 2 to find the cost for 2 bags: Cost for 2 bags = $1.85 × 2 = $3.70. This calculation demonstrates how to determine the cost of a different number of items when given the total cost for a set amount - a common problem solving method used in unit pricing and budgeting exercises.
