Amount of soup made by Joy = 6.5 liters and nearest to 0.5 liters is 7 liters
Amount of soup in each serving portion = 280 ml. As the last digit is zero, this will not be rounded off and nearest value will remain 280
Number of people being served = 22
So total consumption of soup for 22 people is = 
In liters this is = 
Hence, Joy has enough soup for 22 people. 
 
                                
             
                    
              
Answer: 
Joy definitely does have enough soup for 22 people.
Step-by-step explanation: 
Upper Bound: 285ml  turn it to 0.285 L                      10÷2=5
280ml  :
Lower Bound: 275ml turn it  to 0.275 L
Upper Bound: 6.75 L                           0.5÷2=0.25
6.5 Litters  : 
Lower Bound:6.25  L
6.75÷0.275=24.54 or 25  
6.25÷0.285=21.92 or 22

Answer: 
32.5 square feet
Step-by-step explanation: 
The formula for a trapezoid is a= 1/2*(b1+b2)*h. B1 and b2 would represent the two bases given and therefore doesn't matter what order you put them in. Plug in all values into the equation and you'll get 1/2*(5+8)*5 then 1/2*(13)*5. Next simplify to get 6.5*5 which then equates to 32.5.
