Marks: +1, -0

Your Answer:

Validate

Solution:

Twenty percent of the sweaters in the store are white, so there are 200 ×

{20}/{100}

= 40 white sweaters. There are 200 − 40 = 160 sweaters remaining. Of the remaining sweaters, 160 ×

{40}/{100}

= 64 are brown.
That means that 160 − 64 = 96 are blue. There are 96 − 40 = 56 more blue sweaters than white sweaters.
