2. A government buys x fighter planes at z dollars each, and y tons of wheat at w dollars each. It spends a total of B dollars, where
B = xz + yw. In (a)-(C), write an equation whose solution is the given
quantity.
a) The number of tons of wheat the government can afford to buy if it
spends a total of $100 million, wheat costs $300 per ton, and it must
buy 5 fighter planes at $15 million each.
b) The price of fighter planes if the government bought 3 of them, in
addition to 10,000 tons of wheat at $500 a ton, for a total of $50
million.
c) The price of a ton of wheat, given that a fighter plane costs 100,000
times as much as a ton of wheat, and that the government bought 20
fighter planes and 15,000 tons of wheat for a total cost of $90
