Answer$33.60
Step-by-step explanation:
First I added 23 and 6 to get $29
Then I figured out that 20 percent of 23 was 4.6 and added that to 29.
I came out with an answer of 33 dollar and sixty cents.
y = (9x) ^ (1/3)
exchange x and y then solve for y
x = (9y) ^ (1/3)
cube each side
x^3 = 9y
divide each side by 9
1/9 x^3 = y
the inverse function is 1/9 x^3
4x-8 = 31
4x = 31 + 8
4x = 39
x = 9.75
