A verbal description of a function is given. Use a formula to express the function.

You pay \$290 an ounce for high-quality 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 =

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

P=600(s+t)-290s-24t

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.
