Answer :

The cost of eating index increases by approximately 28.6 percent between 2021 and 2022.

To calculate the cost of eating index between 2021 and 2022, we need to compare the total cost of the food basket in both years and calculate the percentage increase.

First, let's calculate the total cost of the food basket in 2021 and 2022.

2021:

Total cost = (Quantity of spinach * Price per kilo) + (Quantity of kale * Price per kilo) + (Quantity of celery * Price per kilo)

Total cost in 2021 = (100 * $6) + (50 * $5) + (80 * $4)

= $600 + $250 + $320 = $1,170

2022:

Total cost = (Quantity of spinach * Price per kilo) + (Quantity of kale * Price per kilo) + (Quantity of celery * Price per kilo)

Total cost in 2022 = (120 * $6) + (60 * $6) + (85 * $5)

= $720 + $360 + $425

= $1,505

Now, let's calculate the percentage increase in the cost of eating index.

Percentage increase = ((Total cost in 2022 - Total cost in 2021) / Total cost in 2021) * 100

Percentage increase = (($1,505 - $1,170) / $1,170) * 100

Percentage increase ≈ 28.6 percent

Therefore, the cost of eating index increases by approximately 28.6 percent between 2021 and 2022.
