Explain why a change from 20 to 40 is a 100% increase, but a change from 40 to 20 is a 50% decrease. Increasing 20 to 40 is the
STALIN [3.7K]

Answer:

To find increase/decrease, divide the starting number by the ending number.

<u>40 to 20</u>

20 ÷ 40 = 0.5

0.5 can be represented by 50%.

<u>20 to 40</u>

40 ÷ 20 = 2

2 can be represented by 200%. This is why decreasing 40 to 20 is a 200% increase. In the wording, it says it's a 100% increase. That would be 20 plus 20 times 1 (which is the same as 100%) which is 40.

Last month Hao dog ate 40 cans of dog food in 31 days. How many cans should Hao buy to feed his for for the next 6 days?
Furkat [3]

we are given

Hao dog ate 40 cans of dog food in 31 days

it means that

31 days =40 cans

Firstly, we will find for 1 day

we can divide both sides by 31

\frac{31}{31} day=\frac{40}{31} cans

1 day=\frac{40}{31} cans

now, we can multiply both sides by 6

6*1 day=6*\frac{40}{31} cans

6days=7.74194 cans

so,

Hao buy to feed his dog  for for the next 6 days is 7.74194 cans.......Answer
