Question

Write an equation to represent Catherine's profit (p) from selling cupcakes for one month Catherine sells cupcakes, c, for 1.50 each. The ingredients for each cupcake cost her $0.30, and the sum of all her other expenses is $20.00/month

Answer 1

Answer:

$\text{p}=\ 1.20\text{c}-\ 20$

Step-by-step explanation:

GIVEN: Catherine sells cupcakes c for $\ 1.50$ each, The ingredients for each cupcake cost her $\ 0.30$, and the sum of all her other expenses is $\ 20/\text{month}$.

TO FIND: Equation to represent Catherine's profit from selling cupcakes.

SOLUTION:

Cost of ingredients for each cupcake  $=\ 0.30$

sum of all other expenses  $=\ 20/\text{month}$

Selling price of each cupcake $=\ 1.50$

Total cupcakes sold $=\text{c}$

Now,

As we know that $\text{Net profit}=\text{Selling price}-\text{Cost price}-\text{Other expense}$

putting values,

                      $\text{p}=\ 1.50\text{c}-\ 0.30\text{c}-\ 20$

                      $\text{p}=\ 1.20\text{c}-\ 20$

Hence the equation  to represent Catherine's profit (p) from selling cupcakes for one month Catherine sells is $\text{p}=\ 1.20\text{c}-\ 20$
