Melanie and Jake are going to give away a king-sized candy bar if the player hits gray, a fun sized Snickers if they hit black and a dum dum if they hit white. They determine that a king-sized candy bar will cost them $1 a piece, a fun sized Snickers costs them $0.25 a piece, and a dum dum costs them $0.05 a piece. If they are charging $1 to play their game what is their expected profit per play?

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
