Q: Bob bought 2 show dogs for $250.00 each to breed as a side business. The female just had a litter of 6 puppies. If he sells each puppy for $350.00, what is his total profit?
A: He bought 2 dogs for $250.00 each so they costs 2 * 250 = $500.00. He sells each of the 6 puppies for $350.00 so he'll make 6 * 350 = $2,100.00. He made $2,100 on the puppies but spent $500.00 to buy the dogs so his total profit is 2,100 - 500 = $1,600.00. The answer is 1600.

Q: Arman is six times older than his sister. His sister is 2 years old four years ago. In how many years will Arman's age be 40?
A:
Arman's sister is 4 + 2 = 6 years old now. So, Arman is 6 x 6 = 36 years old. Hence, Arman will be 40 in 40 - 36 = 4 years. The answer is 4.
