Answer:
The Total earning of Paula riddle from 6 pm to 11 pm is $7.25
Step-by-step explanation:
Given as :
Paula riddle charges per hour before 9 pm = $2.25 per hour
Paula riddle charges per hour after 9 pm = $2.75 per hour
Let The Total earning of Paula riddle from 6 pm to 11 pm = $A
Now, According to question
∵ before 9 pm , charges = $2.25 per hour
The time spend between 6 pm to 9 pm = 3 hours
So, The charge between 6 pm to 9 pm = $2.25 per hours × 3 hours
i.e The charge between 6 pm to 9 pm = $6.75
Again
After 9 pm , charges = $2.75 per hour
The time spend between 9 pm to 11 pm = 2 hours
So, The charge between 9 pm to 11 pm = $2.75 per hours × 2 hours
i.e The charge between 9 pm to 11 pm = $5.5
So, The Total earning of Paula riddle from 6 pm to 11 pm = charge between 6 pm to 9 pm + charge between 9 pm to 11 pm
i.e A = $6.75 + $5.5
Or, A = $7.25
So, The Total earning of Paula riddle from 6 pm to 11 pm = A = $7.25
Hence, The Total earning of Paula riddle from 6 pm to 11 pm is $7.25 Answer
