Answer:
<h3>
1.50X+2.50Y=25</h3><h3>
&</h3><h3>
X+Y=6 are required systems</h3>
(Solution: X=16 and Y=-10)
<u>Explanation:</u>
》Total money that will be spent on flour and corn meal altogether(T)
=$25
》Since it is not mentioned that whether corn and flour are bought in same quantity or not, we will assume them of different quantity.
i.e.,Suppose
》<u>X pound </u>of <u>flour</u> is bought
&
》<u>Y pound </u>of <u>corn</u> is bought.
So,
》Cost of flour(F)=$1.50X
》Cost of corn(C)=$2.50Y
So total cost will be sum of cost of flour and corn altogether,
Writing it in equation(linear),
<u>F+C=T</u>
<h3>
<u>1.50X+2.50Y=25</u></h3>
Also,
Total pounds=6
ie,
<h3>
<u>X+Y=6</u></h3>
All you have to do to find what number a certain number is a certain percentage of is to divide the known number by the percentage that it is reduced by.
To do this, we must first convert the percentage into a decimal. To do this, we can either divide the percentage by 100, or (my personal shortcut) just shift the decimal point over two places to the left.
40% = 0.4
Now, we divide the known by the percentage/decimal.
72 / 0.4 = 180
72 is 40% of 180.

Answer:
The answer to your question is the last option
Step-by-step explanation:
The last option is correct because the point we want to plot is in the third quadrangle where both coordinates (x, y) are negatives.
Also, the last description mentions that we have to move to the left to look for the x-coordinate and after that, we have to move down to look for the y-coordinate.
