Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is

In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Ski
Event B: Snowboard.
28 out of 120 students ski:
This means that 
16 out of 120 do both:
This means that 
P ( snowboard I ski)

So
P ( snowboard I ski) = 0.5714
The equation is
y = $10,000+ $225x
<em>$225 (6) + $10,000 = y</em>
<em>$1,350 + $10,000 = y</em>
<em>$11,350 = y</em>
He will have saved $11,350 dollars in six months.
