Answer:
The Percentage increase in earning of Lorenzo is 25%
Step-by-step explanation:
Given as :
The earning of Lorenzo initial = i = $ 20 per hour
The earning of Lorenzo final = f = $ 25 per hour
Let The Percentage increase in earning = x %
Now, According to question
x% = [tex]\dfrac{\textrm final - initial}{\textrm initial}[/tex]
Or, x% = [tex]\frac{f - i }{i}[/tex]
Or, x = [tex]\dfrac{\textrm25 - \textrm 20}{\tetxrm 20}[/tex] × 100
or, x = [tex]\dfrac{\textrm5}{\tetxrm 20}[/tex] × 100
or, x = [tex]\frac{5\times 100}{20}[/tex]
∴ x = 25%
So, increase = x = 25%
Hence The Percentage increase in earning of Lorenzo is 25% . Answer
