Question

Sherrys family is going to a beach resort. Sherry bought 7 beach towels that cost $13 each to take to the resort. To find the total cost, she added products of 7x10 and 7x3, for a total of $91. What property did Sherry use?

Answer 1

7 × 13 = 7 × (10 + 3) = 7 × 10 + 7 × 3 {By distributive property}

Explanation:

Sherry bought 7 beach towels that cost $13 each to take to the beach resort.

So, the total cost can be obtained by multiplying 7 with 13 which equals to $91.

But she obtained the total cost differently. She added products of 7 × 10 and 7 × 3 and got the same answer $91.

Basically she had used the distributive property of multiplication that made the result equal.

Because, 7 × 13 = 7 × (10 + 3) = 7 × 10 + 7 × 3 {By distributive property}. (Answer)
