Answer
The total cost is \$17.00.
Solution
To determine the total cost of attending the fair and going on rides, let's break down the expenses:
1. **Admission Fee**: \$5.00
2. **Cost per Ride**: \$2.00
3. **Number of Rides**: \( r = 6 \)
**Expression for Total Cost**:
\[
\text{Total Cost} = \text{Admission Fee} + (\text{Cost per Ride} \times \text{Number of Rides}) = 5 + 2r
\]
**Evaluating the Expression for \( r = 6 \)**:
\[
\text{Total Cost} = 5 + 2(6) = 5 + 12 = 17
\]
**Total Cost**: \$17.00

To find the total cost for admission and rides when \( r = 6 \), we first calculate the cost of the rides. Each ride costs \( \$2.00 \), so for 6 rides, the cost is \( 6 \times 2 = \$12.00 \). Now, we add the admission fee of \( \$5.00 \) to the ride cost: Total cost = Admission fee + Cost of rides = \( 5.00 + 12.00 = \$17.00 \). So, the total cost when \( r = 6 \) is \( \$17.00 \).
