Jaco wants to buy Christmas gifts for his 8 friends that are worth $9 each. Also, he wants to buy gifts for his mother and father that are of the same amount. He has a $100 budget to buy all gifts. How much is Jaco's budget for each of his mother and father's gift?
Let's think: Jaco will spend a total of $9 x 8 = $72 for his 8 friends' gifts. He will be left with $100 - $72 = $28 for his mother and father's gift. So, Jaco's budget for each of his mother and father's gift is $28 / 2 = $14.. The answer is: 14.

With 82 students, there are 2 students for each computer. If there are 16 more students, how many computers must they have in total to continue with 2 students per computer?
Let's think: 2 students per computer means the total number of computers is 82 / 2 = 41 computers. with the arrival of 16 students, the number of computers that should be added is 16 / 2 = 8 computers. all computers together are 41 + 8 = 49 computers.. The answer is: 49.

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?
Let's think: 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.

Mason is cleaning out all the junk in his attic. 20% of the items are useful, 10% are valuable heirlooms, and 70% are junk. If Marcus's attic has 8 useful items in it, how many junk items does it have?
Let's think:
First find the total number of items in the attic by dividing the number of useful items by the percentage of useful items: 8 items / .2 = 40 items. Then multiply the total number of items by the percentage that are junk to find the number of junk items: 40 items * .7 = 28 items.. The answer is: 28.
