Answer 1

step by step reading

The coffee variety Arabica yields about 750 kg of coffee beans per hectare, while

Robusta yields about 1200 kg per hectare. Suppose that a plantation has a

hectares of Arabica and r hectares of Robusta.

a. Write an equation relating a and r if the plantation yields 1,200,000 kg of coffee.

b. On August 14, 2003, the world market price of coffee was $1.42 per kg of Arabica

and $0.73 per kg of Robusta. Write an equation relating a and r if the plantation

produces coffee worth $1,200.000. what does that answer that means it would be

ANSWER

a

Arabica coffee = 750a

Robusta coffee = 1200r

The total amount coffee beans

750a + 1200r = 1.200,000 kg

b)

The total amount of market price

1.42*750a + 0.73*1200r = 1,200.000 ⇒

1065a + 876r = 1,200.000 dollar!!!!!!

Answer 2

Explanation:

a)

Arabica coffee = 750a

Robusta coffee = 1200r

The total amount coffee beans 750a + 1200r = 1000000 kg

b)

The total amount of market price

1.42*750a +0.73*1200r 1000000

1065a + 876r = 1000000 dollars
