Let x be the amount of Columbian coffee in the mixture and y the amount of Sumatra coffee in the mixture, then
x + y = 1 . . . (1)
9.25x + 14.25y = 12.50 . . . (2)
(1) x 9.25 => 9.25x + 9.25y = 9.25 . . . (3)
(2) - (3) => 5y = 3.25 => y = 3.25/5 = 0.65
From (1), x + 0.65 = 1 => x = 1 - 0.65 = 0.35
1 pound of the mixture contains 0.35 Columbian coffee and 0.65 Sumatra coffee
Therefore, 12 pounds of the mixture will contain 0.35 x 12 = 4.2 pounds of Columbian coffee and 0.65 x 12 = 7.8 pounds of Sumatra coffee

Step-by-step explanation:
Area of the rectangle:
12 x 15 = 180
Area of semicircle:
π6^2/2 = 56.54866776...
Total area:
180 + 56.54866776...
= 236.55
Answer:
x=28
Step-by-step explanation:
180= 38 + (4x+30)
142= (4x+30)
112=4x
x=28
