Question

he graph shows the relationship between the cost of renting a kayak from the hotel surf shop and the number of hours it is rented.

Complete the table.
Hours 1 2 3 4 5 6
Cost ($)

Note: Use your own words to answer this question.

Answer 1

I can’t see the graph you mention. To complete the table I need either a picture of the graph or at least two clear points from it (for example the cost at hour 1 and hour 4, or the cost at hour 0 and hour 6).

Here’s how you can do it yourself in plain steps:

1. Look at the graph and read off the cost (vertical axis) for each hour 1, 2, 3, 4, 5, 6 (horizontal axis). Fill those numbers into the table directly.
2. If the graph is a straight line (constant rate per hour) you only need two points. Use them to find the rate:
- rate = (change in cost) ÷ (change in hours).
- If the line starts at a nonzero cost when hours = 0, that is a fixed starting fee; the cost formula is Cost = fixed fee + (rate × hours).
- If it starts at 0, the cost formula is Cost = rate × hours.
3. Once you have the formula, compute the cost for hours 1–6 and enter them in the table.

Example (to show the method):
- Suppose the graph shows cost $10 at 1 hour and $60 at 6 hours.
- Rate = (60 − 10) ÷ (6 − 1) = 50 ÷ 5 = $10 per hour.
- Then Cost = 10 × hours, so the table is 10, 20, 30, 40, 50, 60.

Send the graph image or tell me two points from it and I will fill in the table for you.
