Answer:

8 lb of flounder at $2.50/lb

4 lb of shrimp at $5.00/lb

Step-by-step explanation:

Let A be the pounds of shrimp

Let B be the pounds of flounder

Let C be the cost per pound of flounder

A + B = 12

A = 12 - B

BC = 20

A(2C) = 20

BC = A(2C)

BC = (12 - B)(2C)

BC = 24C - 2BC

3BC = 24C

3B = 24

B = 8 lb

A + 8 = 12

A = 4 lb

= 8x - 13

so (f o g) (5)

= 8(5) - 13

Aaliyah is a salesperson who sells computers at an electronics store. She makes a base

hjlf

Answer:

$P=1.25x+70$

Step-by-step explanation:

So we know that Aaliyah earns $1.25 commission for every computer she sells. No matter what, she will make $70 per day, so that would be our constant. The $1.25 would be our independent variable since it can change depending on the amount of computers x she sells. Therefore, our equation is:

$P=1.25x+70$

P represents the total pay, 1.25x represents the total commission for x computers, and the 70 is the base pay.

And we're done!
