The bar chart shows the amount of wheat harvested at three sites from 1990 to 1993. Amount of wheat harvested (tonnes) Key: Site A, Site B, Site C. Year: 1990, 1991, 1992, 1993. Wheat harvested at Site A: 1990 - 6.5, 1991 - 5, 1992 - 4.5, 1993 - 6. Wheat harvested at Site B: 1990 - 1, 1991 - 7, 1992 - 4, 1993 - 5.5. Wheat harvested at Site C: 1990 - 0.5, 1991 - 5.5, 1992 - 4, 1993 - 7.
Answer
The total wheat harvested at Site B from 1990 to 1993 is 17.5 tonnes. This comes from adding 1990 (1), 1991 (7), 1992 (4), and 1993 (5.5): $1 + 7 + 4 + 5.5 = 17.5$ tonnes.
Explanation
What you need to do
You are finding a 4-year total for Site B, so you add Site B’s values for 1990, 1991, 1992, and 1993.
Add Site B’s yearly harvest amounts
From the chart data for Site B:
- 1990: $1$ tonne
- 1991: $7$ tonnes
- 1992: $4$ tonnes
- 1993: $5.5$ tonnes
Now add them: $$ 1 + 7 + 4 + 5.5 = 17.5 $$
Total for Site B
So, the total wheat harvested at Site B over the four years is $17.5$ tonnes.
