To find out how many outfits Sophia needs for one week, we can calculate the total number of outfits she changes into over the week.
-
Calculate outfits for weekdays (Monday to Friday):
- She changes clothes 4 times per day.
- For 5 weekdays, the total is: \[ 4 \text{ changes/day} \times 5 \text{ days} = 20 \text{ changes} \]
-
Calculate outfits for Saturday:
- She changes clothes 2 times on Saturday.
-
Calculate outfits for Sunday:
- She changes clothes 3 times on Sunday.
-
Now, add up all the changes over the week: \[ \text{Total changes} = \text{Weekdays} + \text{Saturday} + \text{Sunday} \] \[ \text{Total changes} = 20 + 2 + 3 = 25 \]
Thus, Sophia needs a total of 25 outfits for one week.
