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.

1 answer

Let's assume that the plantation produces a kilograms of ara coffee and r kilograms of Rob coffee.

The value of the ara coffee produced will be a * $1.42.

Similarly, the value of the Rob coffee produced will be r * $0.73.

Given that the total value of the coffee produced is $1,000,000, we can create the following equation:

a * $1.42 + r * $0.73 = $1,000,000
