Answer:
375 sweaters sold, 125 sweaters did not sell
Step-by-step explanation:
A percent is the piece of the whole or total. 25% decrease means the total of 500 sweaters must be decreased by 25% or 1/4. We multiply 500 by 0.25 and get 125. This means that 125 less sweaters sold then expected. To find the number of sales which did occur we subtract 125 from 500.
500(0.25)=125
500-125=375 sweaters sold
