Cars Airplanes Boats

MATRICES. DETERMINANTS. CRAMER’S RULE?
Ted’s Toys makes toy airplanes, boats, and cars. The materials used are
plastic, wood strips, and steel. Each airplane uses 100 grams of plastic,
25 centimeters of wood strips, and 200 grams of steel. Each boat uses
50 grams of plastic, 250 centimeters of wood strips, and 50 grams of steel;
and each car uses 50 grams of plastic and 150 grams of steel. If Ted’s
has on hand 10,500 grams of plastic, 3,750 centimeters of wood strips,
and 25,500 grams of steel, how many planes, boats, and cars should be
made to use up all these supplies?
Let a = the number of airplanes, b = number of boats, and c = number of cars. The total amount of :
plastic will be 100a + 50b + 50 c = 10,500,
wood strips will be 25a + 250b + 0c = 3750,
steel will be 200a + 50B + 150c = 25,500.
To decrease the size of the numbers involved, let us replace these equations with
2a + b + c = 210
a + 10b = 150
4a + b + 3c = 510.
Now let the determinant of
[2 1 1]
[1 10 0] = D
[4 1 3],
[210 1 1]
[150 10 0] = A
[510 1 3],
[2 210 1]
[1 150 0] = B
[4 510 3],
[2 1 210]
[1 10 150] = C
[4 1 510].
Taking determinants, we find D = 18, A = 900, B = 180, and C = 1800. Now a = A/D = 50, b = B/d = 10, and c = C/d = 100.
