Answer:
A = 80g B = 200g
Step-by-step explanation for A:
First, you would find what the serving size is divided by to get the number of people needed to feed 6/3 = 2. Then take that number (3) and divided it by the fish (240g) to get 240/3 = 80.
Step-by-step explanation for B:
You will first need to find how much butter goes into ONE pie by dividing 80 by 6 which is 1.33333333333333. Then do 1.333333333333333 times the number of people to feed (15) to get 200.
1.06 , 0.90, 0.601, 0.109, 0.07
now, bear in mind that, the population is doubling every half-hour, so, in 3hrs, it doubled 6 times, thus, our time is 6 for 3hrs, since the cycle is every 30mins
now, for 24hrs? well, that's 48 half-hours, thus t = 48
You can rewrite 1 to 100
move the decimal point two places to the right
95% of 100
that is 95
then you move the decimal point back two places
0.95
That is 95% of 1.
Hope this helps :)
