Last year, Yuri earned $51,790 and spent $52,510. Select all the correct statements about Turi's budget

• Yuri was in debt by the end of the year

• Negative numbers should represent Yuri's earnings and spending

• A positive number should represent Yuri's earnings

• A negative number should represent Yuri's spending

• Yuri was able to save some money by the end of the year.

Yuri spent more than she made, so she was in debt (negative money) at the end of the year.

Earnings means how much she got so those are positive numbers

Spending is how much she spent so she is losing money, which means negative.

Which of the following ordered the values from least to greatest? |-9|, -|5|, -|-12|, |-(-14)|

• -|-12|, -|5|, |-9|, |-(-14)|

• -|5|, |-9|, -|-12|, |-(-14)|

• -|-5|, |-(-14)|, -|-12|, |-9|

• |-(-14)|, |-9|, -|5|, -|-12|

Answer explanation

The bars mean abslute value, which is distance from 0 and NEVER NEGATIVE (if the negative sign is INSIDE the bars)

|-9| = 9

-|5| = -5 (negative sign outside)

-|-12| = -12 (negative sign outside)

|-(-14)| = 14

so, least to greatest is -12, -5, 9, and 14
