Let x = the number of liters of 1st drink
y = the number of liters of 2nd drink
Equations
(1) 0.3x + 0.6y = 1,000
(2). 0.7x + 0.4y = 1,500
Multiply equation (2) by 1.5
(3) 1.05x +0.6y = 2,250
Subtract equation (3) by equation (1)
.75x = 1,250
x = 1,667
y = 833
Answer
1,667 liters of 1st drink and 833 liters of 2nd drink should be produced.
Solved.
