Question

Jeanette's sister charges $5.50 per hour before 9:00 pm for babysitting and $8 per hour after 9:00 pm. She finished babysitting at 11:00 pm and earned $38. At what what time did she began babysitting?

Answer 1

Hey there! :D Jeanette's sister started at 5:00 PM. To get that answer, here's what I did:   From 5-9 PM, she earned $22. That's because 5.50 x 4 = 22, then from 10-11, she charged $8 which is 8 x 2 = 16 + 22 = $38. Again, she started at 5 PM.

Hope it Helps and makes sense! :D

Answer 2

She started working at 4:00 pm

Before 9:00 pm she charges $5.50 an hour and after 9:00 pm is $8 and hour.

She worked 2 hours after 9:00 pm so $8 + $8 = $16

$38 - $16 = $22

Divide $22 by $5.50 and you get 4 hours.
