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

    Step-by-step 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)
