Answer:
30
1.301
Step-by-step explanation
f(x) and g(x) are inverse functions. Note that the logrithmic notation for 
So, when x = 1.477, f(x) = y = 30
and when x = 20, g(x) = y = 1.301
.88y +.03y = final cost or more simply .91y = final cost
100% - 12% discount leaves 88% of y (.88y)
3% tax = .03y
.88y + .03y = .91y
Well 1/4 times 7 is 1 3/4 and 7 times 1 is 7 so add 1 3/4 and 7 to get 8 3/4 in.^2

So taking part over the whole month you will get % spent.
375/1500 = .25
Convert to percent by multiplying by 100.
.25 x 100 = 25%
He spends 25% of his income on rent each month.
