Paula Riddle charges $2.25 per hour to babysit before 9:00 P. M. and $2.75 per hour after 9:00 P. M. If she babysits from 6: P. M. to 11:00 P. M., how much will she earn? LOL

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
