Answer:

Percent change in the price paid for a tree is 25%.

Step-by-step explanation:

It is given that:

Amount of tree paid for one week = £16

Amount of tree paid in next week = £20

Change = 20 - 16 = £4

Percent increase = [tex]\frac{Change}{Old\ price}*100[/tex]

Percent increase = [tex]\frac{4}{16}*100[/tex]

Percent increase = 25%

Therefore,

Percent change in the price paid for a tree is 25%.
