Question

Lorenzo earned 20 dollars and hour to mow a yard. Now lorenzo is supposed to trim around the edges of the yard as well, and he makes 25 dollars and hour. What is the percent increase in the amount lorenzo earns

Answer 1

The Percentage increase in earning of Lorenzo is 25%

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% =
`(\textrm final - initial)/(\textrm initial)`

Or, x% =
`(f - i )/(i)`

Or, x =
`(\textrm25  - \textrm 20)/(\tetxrm 20)` × 100

or, x =
`(\textrm5)/(\tetxrm 20)` × 100

or, x =
`(5* 100)/(20)`

∴ x = 25%

So, increase = x = 25%

Hence The Percentage increase in earning of Lorenzo is 25% . Answer
