The consumer price index in Zeropia in 2009 relative to the year 2000 was 1.75, meaning that for every Zeropian dollar spent on consumer goods in 2000, $1.75 on average had to be spent in 2009. In Zeropian dollars, what was the increase in the price of Brand Z running shoes from 2000 to 2009, if these shoes’ price increased precisely according to the consumer price index?

(1) The price of Brand Z running shoes was $91 in 2009.

(2) The ratio of the dollar increase in the price of Brand Z running shoes to the price of the shoes in 2009 was 3:7.

given price increase has happened from 2000 to 2009

#1The price of Brand Z running shoes was $91 in 2009.
so in 2000 price would have been ; 91/1.75 ; 52$ ; increase of 91-52 ; 39$
sufficient
#2
The ratio of the dollar increase in the price of Brand Z running shoes to the price of the shoes in 2009 was 3:7.[/quote]
price increase / price of shoes in 2009 = 3/7
value of price increase and price of shoes is not given ; insufficient
IMO A

I was confused with average mentioned in the statement - meaning that for every Zeropian dollar spent on consumer goods in 2000, $1.75 "on average"

Why we have not considered in the solution?

Can someone please explain?

Someone help me understand.

The increase is 52 Zeropian dollars.
The question stem asks us, "In Zeropian dollars, what was the increase in the price of Brand Z running shoes from 2000 to 2009". We do not know the relation between the Zeropian dollars to USD in current time. Hence why I was confused.
