Hi,
Please read carefully to find my small changes.
The bar graph shows the money spent by various wage groups on fast food per week. Hamburgers are the meals most favored by those high-income individuals spending more than 40 pounds per week (on food?). The average-income group also spends a lot on hamburgers with amounts up to 33 pounds, while low-income workers spend the lowest amount on hamburgers with only 14 pounds per week. Surprisingly, in cthe ase of fish and chips, high-income individuals spend exactly the same amount as compared to low-income individuals. They both spend 17pounds once a week. However, the average-income group spends about 25 pounds per week on fish and chips. The high-income group spends about 19.5 pounds per week on pizzas ,whereas the average-income group spends about 13 pounds per week. Low income individuals spend the least on pizzas.
I wouldn't say it's essential, but I have hyphenated the adjectives 'high-income, average-income, low-income'.
Use a pounds sign instead of the word 'pounds'.
Best wishes, Clive
