You remember seeing this item at both Annie's Attic and Betty's Breakables, but you do not remember the price.

Answer 1

Answer:

1.

                                                                                     Discount

Item                     Original Price            $10.00 off                       40% off

Music box                $60                       60 - 10 = $50        60 * (1 - 40%) = $36

A faux Ming vase    $30                        30 - 10 = $20         30 * (1 - 40%) = $18

2. Go to Betty's Breakables if price is higher than $25.

At $25, both businesses would be offering the same discounted price of $15 because:

Annie = 25 - 10 = $15

Betty's = 25 * ( 1 - 40%) = $15

Betty's discount is proportion based however which means that it reduces more than Annie's will past a certain point. That certain point is if the original price is $25. From here on out, Betty will offer a better discounted price than Annie.

For instance, assume an original price of $50.

Annie = 50 - 10 = $40

Betty's = 50 * (1 - 40%) = $30

Betty will keep offering better prices in this manner for anything above $25.
