Answer:
20 grams
Step-by-step explanation:
Let x be the total allowance of fat
16 grams is 80% of his total allowance
x * 80% = 16
Change percent to a decimal
x *.8 = 16
Divide each side by .9
.8x/.8 = 16/.8
x = 20
Turn f(x) into y so the equation is y=x+2. Now switch their places so it is x=y+2. Now solve for y. The answer is y=x-2.
