Answer:
- <em>An integer is not negative if and only if it is not less than zero.</em>
Step-by-step explanation:
Observing each statement individually:
- <em>An integer is negative if and only if it is not less than zero</em>
A number that is NOT less than 0 is greater than zero. Negative numbers are less than 0, so this is clearly incorrect.
- <em>An integer is not negative if and only if it is less than zero.</em>
A number that is NOT negative is positive. Positive integers are integers greater than zero, so this is also incorrect.
- <em>An integer is not negative if and only if it is not less than zero.</em>
A number that is NOT negative is positive. A number that is NOT less than zero is greater than zero, or positive. This statement is correct.
- <em>An integer is less than zero if and only if it is not negative.</em>
A number that is less than zero is negative, and this statement claims that a number less is only less than zero if it is NOT negative. This is incorrect.
So 32 new desks for $24 each... that would be
32
* 24
_____
768
So $768 total for all the new 32 desks
Hope this helps ;)
Find out what number $350 is 8% of, since he makes 8% commission on sales. In the percent formula: a = pb
a is the part, p is the percent (as a decimal), b is the base
350 is 8% of what number? 350 = 0.08b {substituted given values into percent formula and changed 8% to a decimal}
b = $4,375 {divided each side by 0.08}
He needs to make at least $4375 worth of sales.
