Question

Joy makes 6.5 litres of soup, correct to the nearest 0.5 litre. She serves the soup in 280 ml portions, correct to the nearest 10ml. 22 people order this soup. Does Joy have enough soup

Answer 1

Answer:

Joy has not enough soup

Explanation:

 If Joy is serving correct to nearest 10 with  280 ml maximum.

 Maximum soup served by her in one turn = 290 ml

 Number of people she is serving = 22

 Amount of soup required = 22 x 0.29 = 6380 ml = 6.38  L

 Amount of soup she has = 6.5-0.5 L=6 L

  Amount of soup she has < Amount of soup required

 So, Joy has not enough soup.

Answer 2

Answer:

Yes, Joy has enough soup to serve the people.

Step-by-step explanation:

The volume of soup prepared by Joy is 6.5 litres.

She serves the soup in 280 ml portions to 22 people. So, the total volume of soup ordered = 280 ml × 22

                            = 6 160 ml

Converting the volume of prepared soup to ml,

          1000 ml = 1 litre

So that, volume of prepared soup in ml = 6.5 × 1000

                                   = 6500 ml

Comparing the volume of soup prepared with that ordered, we have;

      volume of soup prepared - volume of soup ordered

                                 =  6500 ml - 6 160 ml

                                = 340 ml

Therefore, Joy has enough soup to serve the people and has a volume of 340 ml remaining.
