Question

Jenna’s science teacher changed the number of assignments for the semester to 85. This is shown as the blue line on the graph.

How many more weeks will it take Jenna to complete all the assignments if she completes assignments at the same rate?

more weeks

Answer 1

I don’t have the graph, so I can’t read the numbers directly. I can’t answer the question without either the image or the specific values from the blue line. Please either upload the graph or tell me:

- two clear points on the blue line (week, assignments), e.g. (2 weeks, 10 assignments) and (6 weeks, 30 assignments), and
- the current week (or the most recent point on the line) if it’s not one of those two points.

If you prefer to do it yourself, here are the steps:

1. From the blue line pick two points (w1, a1) and (w2, a2).
2. Compute the rate (slope) m = (a2 − a1) / (w2 − w1) assignments per week.
3. Find how many assignments Jenna has completed so far (a_current). If a_current is not one of your two points, read it from the graph at the current week w_current.
4. Remaining assignments = 85 − a_current.
5. Additional weeks needed = (85 − a_current) / m.
6. If weeks must be a whole number, round up to the next whole week.

Send the graph or the two points (and current point) and I’ll compute the exact number for you.
