A family of two adults and three children went to a water park. Admission to the water park costs $18 per person. Nora used the expression 2 (18) + 3 (18) to model the total cost for the family, and Alex used the expression 5 (18). Which property of operations makes both of their expressions correct?
associative property
commutative property
distributive property
identity property

Answer

Distributive Property.

Step-by-step explanation:

First you solve for the first equation by multiplying 2 by 18 which is 36. Then 3 times 18 which is 54. Then you add them together to get 90.

Next you solve for the second equation by multiplying 5 by 18 which is 90.

Both of these equations are solved by the distributive property because your distributing the number outside of  the parenthesis.
