Write an equation to represent Catherine's profit (p) from selling cupcakes for one month Catherine sells cupcakes, c, for 1.50

Archy [21]

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

(5x-2) + (2x+6) = 67, so we simplify and solve for x:
7x + 4 = 67 --> 7x = 63 --> x = 9

Now we substitute 9 for x in (5x-2):
5(9) - 2 --> 45 - 2 = 43

The distance between A and B is 43 miles.
