Answer:
Only one student, Melinda used it right.
Step-by-step explanation:
Associative property lets us place our brackets the way we want and the result would be unchanged.
Here: (13 + 15 + 20) + (20 + 47 + 18).
So, we can place the brackets in any form, like (13 + 15) + (20 + 20) + (47 + 18).
There are many ways to do it. Melinda's was is yet another example.
Note that Associative property does not hold for subtraction.
A1 is reflected across line x=-3. First option
Given is :
The annual income of Richard = $34200
Hence, his monthly income becomes =
= $2850
So, the maximum amount that he can spend per month paying off credit cards and loans and not be in danger of credit overload can be a maximum of 20% of this income.
So, 20% of 2850 is = $570
Hence, approximately $570 can be spent a month.
As, the question has no options to choose from, but the question is complete in itself, so this is the best possible answer.
