OGo to Betty's Breakables, if the price is above $37.50 O Go to Betty's Breakables, 40% o" is always better than SS.00 off.Explanation / Answer
(1)
(2) Go to Betty's Breakables if price is above $37.5.
If original price is $37.50, then
Discounted price at Anny's = $(37.5 - 15) = $22.5
Discounted price at Betty's = $37.5 x 60% = $22.5
Therefore, if original price > $37.5, Discounted price will be higher at Anny's and lower at Betty's. Similarly, if original price < $37.5, Discounted price will be lower at Anny's and higher at Betty's.
Original price ($) After $15 off ($) After 40% of ($) Music box 75 75 - 15 = 60 75 x 60% = 45 Faux Ming vase 60 60 - 15 = 45 60 x 60% = 36Related Questions
