I think it’s B but I’m not sure
Hey there! Direct variation, a concept commonly applied to linear equations.
The constant of variation is a concept which simply refers to the change in y, based on the change in x. If this change is constant, then it is a constant of variation.
You can find the constant of variation (usually referred to as 'k') by dividing any point's y-value by its x-value.
In this instance, we have the point (3.5, 14)
14 / 3.5 = 4
The constant of variation for this equation would be 4.
C because square one and 2 are both 100 mm and then you have to add 31 for the middle one
It should be noted that the expected return on each ticket is $3 and the expected profit is also $3.

Calculating the expected value</h3>
From the information given, it was stated that they are selling tickets for $6 each and will sell 900 tickets and that there is one $1,000 grand prize, three $500 second prizes, and twelve $10 third prizes.
Therefore, the expected value will be calculated thus:
E = (1/900 × 1000) + (3/900 × 500) + (12/900 × 10)
E = 2.91 = $3
The expected return on each ticket is $3.
Since the cost of the ticket is $6, the expected profit per ticket will be:
= $6 - $3 = $3
