Question

The freshmen at INCA are having a fundraiser and purchase 1,200 chocolate bars to sell. They pay a fee of $25 to get early delivery so that they can start their fundraiser early. The total cost for the chocolate bars, including the delivery fee, is $745. Write an equation that you could use to solve for the cost of each chocolate bar (c). Then, solve the equation to see how much each chocolate bar costs. (4 points)
Equation- use c for the variable:
Cost of each chocolate bar:

Answer 1

To find the cost of each chocolate bar, we can start by setting up an equation. The total cost includes a delivery fee of $25 and the cost of the chocolate bars.

Let \( c \) represent the cost of each chocolate bar. Since there are 1,200 chocolate bars, the total cost for the chocolate bars would be \( 1200c \).

The total cost equation can be written as:

\[
1200c + 25 = 745
\]

Now, we can solve for \( c \):

1. Subtract the delivery fee from both sides of the equation:

\[
1200c = 745 - 25
\]
\[
1200c = 720
\]

2. Now, divide both sides by 1200 to find the cost of each chocolate bar:

\[
c = \frac{720}{1200}
\]
\[
c = 0.6
\]

Thus, the cost of each chocolate bar is \( \text{\$}0.60 \).

**Equation:** \( 1200c + 25 = 745 \)
**Cost of each chocolate bar:** \( \text{\$}0.60 \)
