The percentage of students that graduated from college that also attended a high school is given as 0.7792 or 77.92 percent.
<h3>How to solve for the probability?</h3>
We have the Prob(attended public school | graduated)
The probability that a person attended public school and graduated as
Prob (P and G) = 0.80 x 0.75
= 0.6
The probability that a person graduated is given as
0.8*0.75 + (1 - 0.8 * 0.85)
= 0.6 + 0.17
= 0.77
Prob(P and G ) /Prob(G)
= 0.6 / 0.77
= 0.7792
The percentage is given as 77.92%

If you want to solve the system of equations it will be:
Step 1: solve the equation for y
y= -19+7 → y= -12
Step 2: substitute y into the equation
-2x+3x(-12)=-19
Step 3: solve the equation for x
x= -17/2
Step 5: the possible solution is the order pair (x,y)
Answer: (-17/2 , -12)
$1.300 x 20%
= $260
Interest in one month =
$260 / 12
= $21,67
