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
