2. a) Bart: 825/3 = 275 therefore Alyssa's share would be 275 x 5 = 1375 and Cody's would be 275 x 2 = 550 Alyssa and Cody expects to receive $1375 and $550 respectively.

b) 140 000/5+3+2 = 140 000/10 = 14 000 therefore Alysa's share of the profit: 14 000 x 5 = 70 000 Bart's: 14 000 x 3 = 42 000 Cody's: 14 000 x 2 = 28 000 check: 70 000 + 42 000+ 28 000 = 140 000 Alyssa would receive $70 000, Bart would receive $42 000 and Cody would receive $28 000.
