Answer:
-3
Step-by-step explanation:
Simplify the following:
(-9 (-5) - 9)/(-12)
-9 (-5) = 45:
(45 - 9)/(-12)
| 3 | 15
| 4 | 5
- | | 9
| 3 | 6:
36/(-12)
The gcd of 36 and -12 is 12, so 36/(-12) = (12×3)/(12 (-1)) = 12/12×3/(-1) = 3/(-1):
3/(-1)
Multiply numerator and denominator of 3/(-1) by -1:
Answer: -3
Answer:

Explanation:
The <em>profit</em> will be the revenue less the cost.
The revenue will be the price times the number of items sold. <em>The price is $40 the piece</em>. Work with a piece.
The total cost of a piece is the sum of the <em>cost of the supplies</em>, the s<em>eller's fees</em> and the <em>shipping costs</em> of a piece:
- Seller's fee: 9% of $40 = 0.09 × $40 = $3.60
- Total cost = $8 + $3.60 + $2 = $13.60
Profit = Revenue - Cost = $40 - $13.60 = $26.40
To find the <em>hourly profit</em> you must divide the profit of a piece by the <em>hours of labor</em> to make a piece.
- Hourly profit = $26.40/1.5hour = $17.60/hour
