$155 / 20 hrs = $7.75 an hr
217-155= $62 how much extra money he will earn
$62 / $7.75 = 8 Hours additional
Answer is 8 Hours
Step-by-step explanation:
y = log2 x
Convert to exponential form
x = 2^y
when x = 8 , 8 = 2^y so y = 3
x = 4 , 4 = 2^y so y = 2
the other values are found in the same fashion.
x = 2 , y = 1
x = 1 y = 0
x = 1/2, y = -1
