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%.
