Homework Statement

The inhabitants of a small island begin exporting beautiful cloth made from a rare plant that grows only on their island. Seeing how popular the small quantity that they export has been, they steadily raise their prices. A clothing maker from New York, thinking that he can save money by "cutting out the middleman," decides to travel to the small island and buy the cloth himself. Ignorant of the local custom of offering strangers outrageous prices and then negotiating down, the clothing maker accepts (much to everyone's surprise) the initial price of 400 tepizes/m^2. The price of this cloth in New York is 120 dollars/yd^2 If the clothing maker bought 500 m^2 of this fabric, how much money did he lose? Use 1 tepiz = .625 dollars and .9144 m = 1 yard.

Homework Equations

The Attempt at a Solution

500ea*400 temizes/m^2*0.625 dollars/tepiz*(0.9144m/1 yard)^2
=$104515.92

500 m^2*(1 yard/.91144m)^2*120=$71759.40

loss=$104515.92-$71759.40=$32756.52

it says its wrong. what am i doing wrong?

500ea*400 temizes/m^2*0.625 dollars/tepiz*(0.9144m/1 yard)^2
=$104515.92

Where are you getting the "ea" at the beginning from?
