Question

A plane flight to Washington D.C costs $200 give or take $50. A plane flight to China costs $1,250 give or take $50. Which plane flight does the $50 relatively affect mort? Explain your reasoning below.

Answer 1

The DC flight

Explanation:

A fixed amount ($50) is always a larger fraction of a smaller number. It is a larger fraction of $200 than of $1250. The plane flight to Washington DC is affected relatively more by a variation of $50.

__

A price change of $50 on a base price of $200 is a percentage change of 25%. 50/200 × 100% = 25%

A price change of $50 on a base price of $1250 is a percentage change of about 4%. 50/1250 × 100% = 4%
