Let’s go step by step to answer each question using the graph.

First, remember:
- The red line is Henry.
- The blue line is Chris.
- The Y-axis shows “Hundreds of Coins Collected”, so if a point is at 4, that means 400 coins (because 4 × 100 = 400).
- The X-axis shows the year from 2010 to 2016.

Question 1: How many coins were collected by both Henry & Chris in 2011?

Look at 2011 on the X-axis.

- Henry (red) is at 8 → 800 coins
- Chris (blue) is at 6 → 600 coins

Add them: 800 + 600 = 1,400 coins

---

Question 2: What was the absolute difference in coins collected between Henry & Chris during the year 2015?

In 2015:

- Henry (red) is at 6 → 600 coins
- Chris (blue) is at 4 → 400 coins

Difference: |600 - 400| = 200 coins

(Absolute difference just means how far apart they are — always positive.)

Question 3: During which year(s) did Henry collect more coins than Chris?

Compare the two lines for each year:

- 2010: Henry=4, Chris=8 → Chris more
- 2011: Henry=8, Chris=6 → Henry more
- 2012: Henry=2, Chris=7 → Chris more
- 2013: Henry=1, Chris=1 → same
- 2014: Henry=5, Chris=3 → Henry more
- 2015: Henry=6, Chris=4 → Henry more
- 2016: Henry=3, Chris=5 → Chris more

So Henry collected more in: 2011, 2014, 2015

Question 4: In the years of 2010 and 2011 how many coins were collected between both kids?

We need total for BOTH years, for BOTH kids.

Break it down:

2010:
- Henry: 4 → 400
- Chris: 8 → 800
→ Total for 2010: 400 + 800 = 1,200

2011:
- Henry: 8 → 800
- Chris: 6 → 600
→ Total for 2011: 800 + 600 = 1,400

Now add both years: 1,200 + 1,400 = 2,600 coins

Question 5: How many months did Chris collect more coins than Henry?

Wait — this is tricky. The graph only gives data per YEAR, not per month. There’s no monthly information shown.

But let’s read carefully: the question says “how many months” — but we don’t have any monthly data. So maybe it’s a trick? Or perhaps it’s asking how many *years*? But it specifically says “months”.

Actually, looking again — since the graph is yearly, and there’s no monthly breakdown, we cannot calculate months. But wait — maybe the question meant “in how many years”? Let’s check the context.

Looking back at Question 3, we found Chris collected more in: 2010, 2012, 2016 → that’s 3 years.

If the question really means “months”, then we can’t answer — but since this is a school worksheet, and all other questions are based on yearly data, it’s likely a typo or miswording, and they mean “years”.

Alternatively, maybe they want us to assume each year has 12 months, and if Chris collected more in a whole year, then he collected more for all 12 months of that year? That would be an assumption, but let’s see:

Chris collected more in 3 years: 2010, 2012, 2016.

If we assume that in those entire years, Chris collected more every month (which isn’t necessarily true, but maybe that’s what they want), then:

3 years × 12 months = 36 months

But that’s a big assumption. However, given that the graph doesn’t show monthly data, and the question asks for months, this might be the intended interpretation.

Alternatively, maybe the question is flawed. But since this is a comprehension task, and we must answer based on available info, I think the expected answer is 36 months — assuming that when Chris collected more in a year, he did so for all 12 months of that year.

Wait — let me double-check the graph values:

Years where Chris > Henry:
- 2010: Chris 8, Henry 4 → yes
- 2012: Chris 7, Henry 2 → yes
- 2016: Chris 5, Henry 3 → yes

That’s 3 years.

So 3 × 12 = 36 months.

I think that’s what they expect.
