Answer:
(12$ + 24$) + 6$ = 12$ + (24$ + 6$)
Step-by-step explanation:
Since, we know that we want the total amount spent, we can find that by adding the amount of cake and hot dogs and hamburgers first i.e.
12$ + 24$ = 36$
and then adding the cost of drinks i.e. 6$ to the sum of amount of cake and hot dogs and hamburgers i.e.
(12$ + 24$) + 6$ = 36$ + 6$
(12$ + 24$) + 6$ = 42$
We can find the total amount spent by one more method i.e. adding the amount of hot dogs and hamburgers and drinks first i.e.
24$ + 6$ = 30$
and then adding the cost of cake i.e. 12$ to the sum of amount of hot dogs and hamburgers and drinks i.e.
12$ + (24$ + 6$) = 12$ + 30$
12$ + (24$ + 6$) = 42$
Since the total amount spent found by both method are same, thus we can say that:
(12$ + 24$) + 6$ = 12$ + (24$ + 6$)
