Concrete is a mixture of Portland cement, sand, and gravel. A distributor has three batches for contractors. Batch 1 contains cement, sand, and gravel mixed in proportions 1/8, 3/8, 4/8; batch 2 has the proportions 2/10, 5/10,3/10; and batch 3 has the proportions 2/5, 3/5, 0/5. It is known that the total amount of cement used in batches is equal to 2.3 cubic yards. The total amount of sand and gravel are given to be 4.8 and 2.9 cubic yards respectively. Calculate the amount of each batch by introducing matrix operations. Hint: write down the equations first.
