Question

#35 Two companies with top revenues in the fortunate 500 list for 2012 were Exxon Mobil and Wal-Mart. Their revenues together totaled $919.1 billion. Exxon Mobil revenues were $19.3 billion less than those of Wal-Mart. What were the revenues of each corporation?

Answer 1

let walmart = y

Exxon = x

x +y = 919.1 billion

x = y-19.3 billion

so y-19.3 +y = 919.1

2y-19.3=919.1

2y = 938.4

y=469.2 billion ( Walmart)

x= 469.2 -19.3 = 449.9 billion (Exxon)
