Question

Name Multiply with 9 1 MP Use Structure A store is open 9 hours each day. It is open 6 days each week. How many hours is the store open each week? Explain how you can find the answer using the Distributive Property with multiplication and subtraction.​

Answer 1

To calculate how many hours the store is open each week, multiply the daily open hours (9) by the number of days open per week (6), resulting in 54 hours.

Step-by-step explanation:

• To find out how many hours the store is open each week, we can multiply the number of hours the store is open each day by the number of days it is open per week.
• The store is open 9 hours each day and 6 days each week.
• Using the Distributive Property of multiplication, we could express this as 9 hours/day × (5 days + 1 day).
• We could first multiply 9 hours/day × 5 days to get 45 hours, then add the extra day with 9 hours/day × 1 day = 9 hours.
• Adding these together, 45 hours + 9 hours, gives us a total of 54 hours per week.
• However, in this specific case, applying the Distributive Property might be unnecessary since the calculation is straightforward without breaking down the days.
• The direct multiplication of 9 hours/day × 6 days = 54 hours per week will yield the same result.
