Answer 1

Q1.

Number of white female students = 3,400

Total number of students = 17,000

The fraction of student body that is white and female = Number of white-female students/Total number of students = 3,400/17,000 = 1/5

Ans: 1/5

Q2.

Discount offered in Annie's Attic = $20.00

Discount offered in Betty's Breakables = 40%

Music Box:

Original Price of Music Box = $80

Promotional price in Annie's Attic = $80 - $20.00 = $60.00

Promotional price in Betty's Breakables = $80 - 40%*$80 = $80 - 0.40*$80 = $80 - $32.00 = $48.00

Faux Ming vase:

Original price of a faux Ming vase = $60.00

Promotional price in Annie's Attic = $60.00 - $20.00 = $40.00

Promotional price in Betty's Breakables = $60.00 - 40%*$60.00 = $60.00 - 040*$60.00 = $60.00 - $24.00 = $36.00

Q3.

40%*$50 = 0.40*$50 = $20

Therefore, below the price of $50.00, it is better to have a lump sum discount of $20 i.e., Go to Annie's Attic

If the price is above $50.00, it is better to have 40% discount i.e., Go to Betty's Breakables

Ans: Go to Betty's Breakables, if the price is above $50.00
