A verbal description of a function is given. Use a formula to express the function.
You pay $290 an ounce for highquality silver for making jewelry. You pay an average of $24 per ounce for turquoise. You sell your completed jewelry for $600 per ounce. Find the net profit P, in dollars, you make using s ounces of silver and t ounces of turquoise.
P =
Thank you for the opportunity to help you with your question! Hope your day is going well!
well let's write what we do know.
s=ounces of silver
t= ounces of turquoise
Ounces of silver =290 per ounce or in other words 290s
ounces of turquoise= 24 per ounce or in other words 24t
Since you have to pay for the ounces of silver, we know that
you have to subtract 290s
Same logic applies for the ounces of turquoise
But, you make 600 per ounce sold. So, you would need to add (s+t)x600.
So your complete formula for P is as follows
ANSWER
P=600(s+t)290s24t
EXAMPLE
To show you how my formula works, lets use the example that I sold 1 ounce of silver and 1 ounce of turquoise.
well I sold two ounces (1+1)=2
P=600(2)290(1)24(1)=886
Thus the profit would be 886.
