Answer:
y = 9x + 50
Step-by-step explanation:
No choices but an equation would be:
y = 9x + 50
Let
x---------> <span>The probability that a student takes Spanish
y-------> </span><span>the probability that a student takes Drivers Education given that the Student is taking Spanish
z-------> </span><span>The probability that a student at school takes Drivers Education and Spanish
we know that
z=x*y------> solve for y
y=z/x
z=87/1000
x=68/100
substitute
y=(87/1000)/(68/100)-----------> y=87/680
the answer is
87/680</span>
