To find the cost per day and the booking fee, we can use the information provided in the table.
Let’s denote:
- \( B \) as the booking fee,
- \( C \) as the cost per day.
We have the following equations based on the number of days and total cost:
1. For 4 days:
\( 4C + B = 675 \) (Equation 1)
2. For 5 days:
\( 5C + B = 800 \) (Equation 2)
3. For 6 days:
\( 6C + B = 925 \) (Equation 3)
Now, let's solve these equations.
**Subtract Equation 1 from Equation 2:**
\[
(5C + B) - (4C + B) = 800 - 675
\]
This simplifies to:
\[
C = 125 \quad (1)
\]
**Subtract Equation 2 from Equation 3:**
\[
(6C + B) - (5C + B) = 925 - 800
\]
This simplifies to:
\[
C = 125 \quad (2)
\]
Now that we know \( C = 125 \), we can substitute this value back into one of the equations to find the booking fee \( B \). Let's use Equation 1:
\[
4C + B = 675
\]
Substitute \( C = 125 \):
\[
4(125) + B = 675
\]
\[
500 + B = 675
\]
Now solve for \( B \):
\[
B = 675 - 500
\]
\[
B = 175
\]
Thus, the cost per day is \( \text{\$125} \) and the booking fee is \( \text{\$175} \).
**Final answer:**
- The cost per day is **$125**.
- The booking fee is **$175**.
Let’s denote:
- \( B \) as the booking fee,
- \( C \) as the cost per day.
We have the following equations based on the number of days and total cost:
1. For 4 days:
\( 4C + B = 675 \) (Equation 1)
2. For 5 days:
\( 5C + B = 800 \) (Equation 2)
3. For 6 days:
\( 6C + B = 925 \) (Equation 3)
Now, let's solve these equations.
**Subtract Equation 1 from Equation 2:**
\[
(5C + B) - (4C + B) = 800 - 675
\]
This simplifies to:
\[
C = 125 \quad (1)
\]
**Subtract Equation 2 from Equation 3:**
\[
(6C + B) - (5C + B) = 925 - 800
\]
This simplifies to:
\[
C = 125 \quad (2)
\]
Now that we know \( C = 125 \), we can substitute this value back into one of the equations to find the booking fee \( B \). Let's use Equation 1:
\[
4C + B = 675
\]
Substitute \( C = 125 \):
\[
4(125) + B = 675
\]
\[
500 + B = 675
\]
Now solve for \( B \):
\[
B = 675 - 500
\]
\[
B = 175
\]
Thus, the cost per day is \( \text{\$125} \) and the booking fee is \( \text{\$175} \).
**Final answer:**
- The cost per day is **$125**.
- The booking fee is **$175**.
