Step-by-step explanation: Meeeeoooowwww!
You would take 20 × .2 and then take that awnser and add it to 20 dollars, then ÷that awnser by 2 and you will get your final amount. ( awnser: $12.00 )
The number of people increased by 2.
This means as a ratio it is now 6/4 as many as originally planned.
6/4 can be reduced to 3/2.
The time and the number of people are inversely proportional, so the food would last 2/3 ( inverse is flipping the original ratio over) the original length of time.
This means the length of time the food lasts is reduced by 1/3, which is 33.3%
