Sure! Here are the answers and explanations for the questions provided:

### Question 3
Based on the given data:

To find the equation of the relationship between borrowed amount (x) and repaid amount (y), we can set up the ratios or find a pattern.

1. Calculate the ratio of amount repaid to the amount borrowed for the first row.

Example: For $100 borrowed, the amount repaid is $135.
Ratio = \( \frac{135}{100} = 1.35\) (which can also be viewed as a slope)

2. Then for all rows, this should be consistent. The linear equation can be represented as \( y = mx + b \)

After analyzing the data:

- The factor for y can be deduced from the differences; when simplified, one might derive:

\[ y = \frac{5}{4}x + 10 \]

Therefore, the correct response is:
**y is equal to 5 fourths x plus 10.**

### Question 4
Without the graph, I cannot fill in specific values, but typically you could evaluate the relationship between x and y based on the known values, then interpolate or extrapolate to find y values.

### Question 5
The graph representing the relationship \( y = 0.05x \) would be a straight line through the origin, indicating that for every additional can, the earned money increases by $0.05.

### Question 6
For Movies Plus:
- Monthly service: $10
- Cost per movie: $2
For 15 movies:

Total Cost = \( 10 + (15 * 2) = 10 + 30 = 40 \)

For Movies for Less:
- Cost per movie: $3
For 15 movies:

Total Cost = \( 15 * 3 = 45 \)

Thus, when purchasing 15 movies, Movies for Less costs $5 more than Movies Plus.

### Question 7
If the admission cost is $8 per person, the total cost `y` can be expressed for `x` (number of friends):

- For 2 friends: \( y = 2 * 8 = 16 \)
- For 3 friends: \( y = 3 * 8 = 24 \)
- For 4 friends: \( y = 4 * 8 = 32 \)
- For 5 friends: \( y = 5 * 8 = 40 \)

Ordered pairs:
**(2, 16), (3, 24), (4, 32), (5, 40)**

### Question 8
Calculate the shipping cost for 7 pounds:

Cost = Base Fee + (Cost per pound * Weight) = \( 5 + (1.5*7) = 5 + 10.50 = 15.50 \)

For 10 pounds:

Cost = \( 5 + (1.5*10) = 5 + 15 = 20 \)

So:
Derek pays $15.50, and Keisha pays $20; hence Keisha spent $4.50 more than Derek.

### Question 9
Set the two equations for total costs to find their equivalences based on `n` visits.

To check when both costs will equal:
\[ 6n = 50 + 5n \]
\[
n = 50 \text{ when both cost } = 300 \text{ dollars for 50 visits.}
\]

So:
**The total yearly cost is $300 at each gym for 50 visits.**

### Question 10
For a group of 3 friends and riding 8 rides each:
Costs:
Admission: \( 3 * 8.25 = 24.75 \)
Rides: \( 3 * 8 * 1.50 = 36.00 \)

For riding 3 rides each:
Rides: \( 3 * 3 * 1.50 = 13.50 \)

Difference in total costs between 8 and 3 rides = \( (24.75 + 36.00) - (24.75 + 13.50) = 22.50 \)

### Question 11
Substituting \( y = 0.8 \) into the equation:

\[ 4x + 8(0.8) = 40 \]
\[ 4x + 6.4 = 40 \]
\[ 4x = 33.6 \]
\[ x = 8.4\]

### Question 12
Total number of miles equation:
\[ 5x + 10y = 90 \] (based on trail distances)

### Question 13
Correct equation:
\[ 1.49y + 1.25x = 100 \]
Error in not including both x and y in her total sales equation.

Correct response:
**Barbara’s equation did not consider the number of bottles of iced tea.**

### Question 14
Substituting \( y = 4 \):
\[ 8x - 2(4) = 48 \]
\[ 8x - 8 = 48 \]
\[ 8x = 56 \]
\[ x = 7. \]

Thus answers 1 by 1 for the questions summarized.
