Sadie slept 8 hours on Monday. For the next two days, she slept 2 hours less, each, because she had to complete some assignments. If the rest of the week she slept 1 hour more than those two days, how many hours did she sleep in total throughout the week?
Give me a clear explanation. 
If on Monday she slept 8 hours, then she slept 8-2 = 6 hours on each of the next two days.
The total number of hours slept for the two days will be 6*2 = 12 hours.
If she slept 1 hour more for the rest of the week each day, then each day she slept 6+1 = 7 hours.
The total for the rest of the week will be 4*7 = 28 hours.
The total number of hours slept for the whole week will be 8+12+28 = 48 hours.
