Answer 1

1)

Difference is given in percentage terms. It means that difference will be higher if cost is higher.

Correct option is

greater

2)

		Discount
Item	Original Price (Dollars)	$20.00 off (Dollars)	40% off (Dollars)
A music box	80	80-20=60	80*(1-40%)=48
A faux Ming Vase	60	60-20=40	60*(1-40%)=36

First we estimate the original price,x , at which after discount price is same. i.e.

x-20=x*(1-40%)

x-20=0.6x

0.4x=20

x=$50

It indicates that after discount price is cheaper at Betty's Breakables if original price is higher than $50.

So, customer should buy from Betty's breakables if original price is higher than $50 otherwise from Annie's Attic.

At a price of $50, customer can choose any store.
