, and the sum of all her other expenses is
.
TO FIND: Equation to represent Catherine's profit from selling cupcakes.
SOLUTION:
Cost of ingredients for each cupcake
sum of all other expenses
Selling price of each cupcake
Total cupcakes sold
Now,
As we know that
putting values,
Hence the equation to represent Catherine's profit (p) from selling cupcakes for one month Catherine sells is
There are 3 ways of solving a simultaneous problem, substitution method, elimination method and Gauss-Jordan method. I'm gonna use the substitution method since it's easier and i think it would suit your level more.
First let's try solving for y since it's easier to start with.
Firstly we have to find an equation for x:
Great, now we can use the substitution method to find the value of y using the first equation:
Now we know that y=1 we can solve the first equation we made:
And the answer is
Double check:
And that's our final answer! (4,1)
