Given function is a direct variation

Step-by-step explanation:

The direct proportion is defined as the increase in one quantity causes increase in other quantity.

If y is directly proportional to x, then it is given as:

y = kx

where k is the constant of proportionality

Given

y = 3x

Comparing the general form and given equation we see that both are same where k =3

So,

Given function is a direct variation

Poppy felix and Alex sell 700 raffle tickets between them.

prohojiy [21]

First 700-25=675

Poppy= 2F (F as in Felix, since she sells twice as much)
Alex = (Now equals 2F as well, cus we already took away the 25)
And well.... Felix is just felix so add that all up

F+F+F+F+F=5F

675/5=135!
Now according to that 135 is how many felix sold

Felix=135
Poppy=270
Alex=295
