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!

Answer:

B. 4/3

Step-by-step explanation:

Tan is Opposite over Adjacent (SOH CAH TOA), so you would have to take the opposite (36) and put it over the value of the side adjacent to X (27).

36/27 simplifies to 4/3 if you divide both the numerator and denominator by 9.

Your final answer is b (4/3)
