Question

On August 12, 2003, the world market price of coffee was $1.42 per kg of ara and $0.73 per kg of Rob. Write an equation relating a and r if the plantation produces coffee worth $1,000,000.

Answer 1

1.42 per kg of ara=1.42a

0.73 per kg of rob=0.73r

If the sales of both add up to 1,000,000, we can form the equation:

1.42a+0.73r=1,000,000
