Question

Movie ticket prices have been on a steady rise the past few years. Five years ago the ticket price was p = price. Two years ago prices increased by $2 a ticket and this year they have increased by $1. The ticket price change could be expressed as (p + 2) + 1.
Use the associative property to write an equivalent expression.
A) p = 2 + 1
B) p + (2 + 1)
C) 2p + 1
D) p(2 + 1)

Answer 1

Associative property is fun. My old teacher would tell me that when you use the associative property YOU CAN GO CRAZY WITH PARENTHESIS. Associative property is changing the parenthesis. The answer is b because a and c have no parenthesis and d is multiplication and were adding so b is equivalent <span />

Answer 2

The answer would be B) p+(2+1)
