Joy prepares 6.5 liters of soup, rounded to the closest 0.5 liters, which approximates to 7 liters.

Each serving size of soup is 280 ml; since it ends with zero, this value remains unchanged when rounded.

The soup is intended to serve 22 individuals.

Thus, the total volume of soup consumed by 22 people is:

$22\times280=6160$ = 6160 ml

Converted to liters, this equals $\frac{6160}{1000}=6.160$ liters.

Therefore, Joy has sufficient soup to serve all 22 people.

Answer:

Joy does have enough soup to serve 22 people.

Detailed steps:

Upper bound volume per serving: 285 ml = 0.285 L 10 ÷ 2 = 5

Nominal volume per serving: 280 ml

Lower bound volume per serving: 275 ml = 0.275 L

Upper bound total soup volume: 6.75 L 0.5 ÷ 2 = 0.25

Nominal total soup volume: 6.5 L

Lower bound total soup volume: 6.25 L

Calculating maximum number of servings: 6.75 L ÷ 0.275 L = 24.54 ≈ 25 servings

Calculating minimum number of servings: 6.25 L ÷ 0.285 L = 21.92 ≈ 22 servings
