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.
5/12 = 0.4166666...
That is what it says on the calculator.

=> 7.5
Answer:
C.
Step-by-step explanation:
If f(c)=0 then (c,0) is on the graph.
In general, if f(a)=b then (a,b) is on the graph.
By factor theorem if f(c)=0 then x-c is a factor.
If x-c is a factor then x-c will divide f(x) evenly. We know this because the remainder will be 0 because we know x-c is a factor of f.
The only choice that I have said in this whole thing that is true is C.
Answer:
<h2>$87.32</h2>
Step-by-step explanation:
Step one:
given data
we are told that the initial bill is $74
thereafter they gave a tip worth 18% of the bill
let us compute what 18% of $74 will amount to
Step two:
=18/100*74
=0.18*74
=$13.32
The added expenses is $13.32
Hence the total cost is
the initial bill plus the tip
=74+13.32
=$87.32
