dinorap1 · Answer

The only ones I'm unsure about are 1 and 3.

thesmartone · Answer

I'm not really sure about #1, but #2 and #3 are definitely correct. :)

rhondasommer · Answer

#1 and #2 are correct. I keep getting different numbers than the options for #3 but whatever

dinorap1 · Answer

How do you calculate percentages? I got A for number 3 by multiplying .75 to 18.95.

thesmartone · Answer

Ohhhh, my bad. #3 is wrong.

It's on a 75% sale. That means you have to pay 25% of the original cost.

0.25 * 18.95 = ??

thesmartone · Answer

Also, x% means x/100

To make y which is a number into a percentage, you just multiply it by 100 and slap the percentage sign next to it

dinorap1 · Answer

Ahhh, thank you so much. I knew 3 couldn't be right. It didn't make sense, that's why I posted it here.

So that's how you calculate percentages? Thanks for explaining!

rhondasommer · Answer

lol i was like...uhhhhh

dinorap1 · Answer

So 3 is C. I'm pretty sure number 1 is correct, since the other answers for that question don't make sense.

I do like the "press any function key" option though. Just pick one at random. Spin the wheel, let it ride! Live life on the edge! Pee into the wind!
