Somente estudam = 50 - 15 = 35

Somente jogam = 25

Nem estudam nem jogam = 5

The final cost of a sale item is determined by multiplying the price on the tag by 75%. Which best describes the function that r
scoundrel [369]

First we try to frame the equation between the sale price and the final cost.

Let us consider, the price to be x and the final cost to be y, since the final cost is 75% of the price, we have the below equation

y = 0.75x

This is of the form of straight line equation y = mx +c where c =0 and m = 0.75

This means the function is linear since it satisfies a straight line equation.

So, we can eliminate options (3) and (4)

Now, the function is not a continuous one because the function is has definite value which is 0.75x and this make the function discrete. Hence option (2) is eliminated

Therefore we are left with option (1) which is the answer

Answer is (1) It is linear because the ratio of the change in the final cost compared to the rate of change in the price tag is constant
