Answer:
Each sweater costs $35.
Step-by-step explanation:
First subtract the total price ($160) by the price of the shirt ($20).
160 - 20 = 140
Now were left with $140. Since Katie bought 4 sweaters, divide 140 by 4.
140/4 = 35
This means that each sweater was $35. If you want to make sure this is correct just multiply 35 by 4 and then add the $20. You should end up with $160.
35 x 4 = 140
140 + 20 = 160

b) Since the sixth student is 50 minutes, which is higher than the mean of 45 minutes, this will bring the over all mean higher that 45 minutes. Also, since 50 falls within the standard deviation range (35 to 55), this mean the new standard deviation will be smaller than 10.
