i'm willing to beat everyone at #10

so, A=72 degrees

divide 72 by 360 degrees, which equals:

0.20571428571

move decimal to the RIGHT (not left,titanium rome), and that would be 20.571428571%

so, overall, the answer would be A is 20% of the entire circle

p.s. to me the picture looks to me more like discongruent pizza slices

better get the larger one:E

Correct method HeatherF, though something went slightly awry in your calculation of 72/360, which is exactly 0.2, not 0.20571428571 !!

alright, let's go and fight #1, which in my personal opinion, is the easiest cuz it involves only one thing: MONEEEEEEEEY! \$\$\$\$\$\$\$\$\$\$\$

well anyways, let's stop goofing around.

so, the monthly salary for Jack is \$78,000 (which is honestly stupid, he should get paid more money)

and, 20% is spent on food (food's good)

and 20% of the 78 000 cash is: \$14,400 (that's a lot of money for food, i can buy like about 20 iphones with that cash)

so, 72,000-14,400 equals: \$57600

then 10% on house rent (it should be 5%, but that's life. people rip you off)

and 10% of 72,000 is:7,200

so, \$57, 600-7,200 would equal: \$50400

okay, thats part I

part II, he now has \$50, 400, and what does he do with that cash?

he spends 30% OF THE REMAINING on his only son's education (well, it actually should be 50% anyways, it's callled trading, but that'slife)

and 30% of 50, 400 equals: 15120

and 50, 400 - 15,120 = \$35280

then he spends 10% of the rest on charity (yay, charity! helping people out!)

and 10% of 35 280 equals: 3,528

so, 35,280 - 3, 528 equals: \$31752

overall, his monthly savings is \$31, 752 (that's less than 50% of what he started with, what the heck? well, thats life again)

and so overall, the answer is: E (NONE OF THE ANSWERS ABOVE)

and actually, his "savings" are spent on me, cuz i stole all the money

Cops: Titanium Rome, you're under arrest for stealing Jack from Titanic's money!

Me: omg! must get rid of the evidence, or maybe run before they catch me!
