The preliminary cost for a 50,000 ft² aircraft hangar must be estimated. 

(a) The first unit estimate was $98.23 per square foot. Estimate the cost of the hangar.

(b) The budget limit came in at $4 million. Perform two analyses: determine the maximum allowed size to be within budget at the first estimated unit cost, and determine the maximum unit cost to stay within budget and maintain the 50,000 ft² size.
