Hello there.
<span>1. Lucy has a jewelry business. To make a certain necklace, she spends $3.38 on materials and $5.57 on labor. She then sells the necklace for $15.99. Lucy’s profit on the necklace is equal to the sale price minus the cost of materials and labor.
</span><span>
(a)How much profit does Lucy earn when she sells a necklace? What fraction of the sale price of the necklace is profit? Record your answer as a fraction using whole numbers.
</span>the fraction of the sale price of this necklace would be (704/1599).
<span>c) Lucy collected $223.86 selling necklaces at a craft fair. How many necklaces did Lucy sell? How much profit did she earn?
</span>223.86/15.99=14 necklaces. 14(7.04)=$98.56 of profit.
Answer:
D.The right hand side value of 150 for constraint 3 can be increased by at most 50 without changing the optimal corner point.
Explanation:
To maximize 10X1 + 7X2 + 5X3; subject to the constraints: X1 + X2 + X3 <= 100; 2X2 + X3 >= 70; -X2 + X3 <= 150, the right hand side value of 150 for constraint 3 can be increased by at most 50 without changing the optimal corner point.
Answer:
Step-by-step explanation:
sin (2x+14)=cos(x-5)
or 2x+14+x-5=90
3x=90-9=81
x=81/3=27°
An appropriate unit for Abedabun's purpose would have to include $ for the car's maintenance COST and a large distance measurement because we are talking about cars (and they can travel a long distance).
The best answer would be:
C) $/km
$ for the cost and km for the distance the car is driven.
