Question
Jennifer's family is going to a beach resort. Jennifer bought 7 beach towels that cost $ 13 each to take to the resort. To find the total cost, she added the products of 7 × 10 and 7 × 3, for a total of $91. The property used by Jennifer is _____________.
- Commutative Property of Multiplication
- Commutative Property of Addition
- Commutative Property of Addition
- Distributive Property
Hint:
Distributive Property states that when a number is multiplied by the sum of 2 numbers, the first number can be distributed to both of those numbers and multiplied by each of them separately, then adding the 2 products together for the same result as multiplying the first number by the sum.
The correct answer is: Distributive Property
Distributive property a (b + c) = ab + ac
7 (10 + 3) = (7 x 10) +( 3 x 10)
= 70 + 30
Keep the distributive property of multiplication in mind.
