An Economy Has Three Industries: A, B, and C

Short Answer

An economy has three industries: A, B, and C. These industries have annual consumer sales of 45, 37, and 64 (in millions of dollars), respectively. In addition, for every dollar of goods that A sells, A requires 25 cents from B and 15 cents from C. For each dollar of goods that B sells, B requires 35 cents from A and 25 cents from C. For each dollar of goods that C sells, C requires 20 cents from A and 45 cents from B. Let a, b, c be the total output from industries A, B, C, respectively. What values of a, b, c (rounded to the nearest thousand dollars) will satisfy both consumer and between-industry demand?
