To find how many cupcakes Ling must sell to break even, you will create an equation where the functions are equal.
0.25x + 30 = 1x; then solve the equation for x, the number of cupcakes.
0.25x + 30 = 1x
-0.25x -0.25x
<u>30</u> = <u>0.75x</u>
30 30
x = 40
Ling will need to sell 40 cupcakes.
<u>2x
</u> 2
The 2's will reduce down to 1's
<u>1x</u>
1
<em><u>x</u></em>
