Find the difference between the numbers, so in this case, 29-25= 4. Take the difference which is 4 and divide by the original amount so 4/25= .16 Finally, you multiply the number by 100 so .16 * 100= 16. The percent increase is 16%.

(6 + 7) + 8 = 21
Travka [436]

Answer: 6+(7+8)=21

Step-by-step explanation:

1. By definition, the associative property of addition is:

(a+b)+c=a+(b+c)

This property says that you can group the numbers in different ways and you will obtain the same result.

2. Therefore, if you have the following expression:

(6+7)+8=21

You apply  the Asociative property of addition by regrouping the numbers as following:

6+(7+8)=21

3. Then, you can conclude that the correct option is B.
