Which equation below would result in the highest earnings, y, when the number of hours worked, x, is 20?

BartSMP [9]

Answer:

(B)

Step-by-step explanation:

(A)The given equation is:

$y=2x^2$

Substituting the value of x=20, we get

$y=2(20)^2$

$y=2(400)$

$y=800$

(B) The given equation is:

$y=2^x$

Substituting the value of x=20, we get

$y=2^{20}$

$y=1048576$

$y=2x+2$

Substituting the value of x=20, we get

$y=2(20)+2$

$y=42$

(D) The given equation is:

$y=|2x|$

Substituting the value of x=20, we get

$y=|2(20)|$

$y=40$

Thus, the equation $y=2^x$ results in the highest earning y.
