That answer guy -_-

OpenStudy (anonymous):

student 92 the answer would be 2 for $.029

Okay, Arias, the key to this one is not to be confused by the switch between dollars and cents. This is labeled as dollars. So you have to ask yourself which place is exactly one cent. Is a cent one tenth of a dollar? .1? Or one hundredth of a dollar? .01?

OpenStudy (anonymous):

Or is it one thousand of a dollar? 0.001?

OpenStudy (anonymous):

.01

OpenStudy (anonymous):

Cool, so that is the place you round to. The 2 is in that place, and we decide whether to round down to 0.02 or up to 0.03.

OpenStudy (anonymous):

so the answer is .01 right

OpenStudy (anonymous):

Noo. Here's how we round. 1) Find the place you're rounding 2) Look one place after that: Is it 5 or higher? No- Round down. The place you are rounding stays the same. Everything after it goes away. Yes- Round up. The place you are rounding goes UP. Everything after it goes away.

No the answer is 3 since .9 is closer to 1 rather than 0
