Answer:

-2 = 4+x2

16 = -15 + y2

Step-by-step explanation:

xm, ym = (x1+x2)/2 , (y1+y2)/2

xm = (x1+x2)/2

ym =  (y1+y2)/2

substitute in what we know

-1 = (4+x2)/2

8 =  (-15+y2)/2


multiply each equation by 2

-2 = 4+x2

16 = -15 + y2

D. Spend 20 percent on food and 5 percent on gas.

Answer:

Spend 10% on clothing and 10% on entertainment

Step-by-step explanation:

Before answering this question, you need to know 2 types of expenses:

1. Fixed

2. Variable

Fixed expenses is the obligatory expenses which we do not have much control, and usually we have to pay in a certain amount of type. For example rent, student loan, grocery etc. In this case, the only fixed expenses is rent which you have to pay every month.

The other options: entertainment, clothing,food and gas are considered variable as it is not obligatory and you can choose how much you would spend.

Option C is not applicable since rent is a fixed expenses and can't be easily change.

Between A, B and C, A is the less amount of percentage compared the other.
