Answer: The value of b is $0.15.
Step-by-step explanation:
Total bottles co0llected = 14+9 =23
Payment for each bottle = b
Total payment she will get = 23b
One -time service fee = $0.25
She has left = $3.20
According to the question,
23b - 0.25 = 3.20
⇒23b = 3.20+0.25
⇒23b = 3.45
⇒b = 0.15 [divide both sides by 23]
Cost of each bottle = $ 0.15
hence, the value of b is $0.15.
profit on the twenty-five $50 radios
= 25*(50*0.08)=$100
Loss on the six $30 radios
= 6*(30*0.15) = $27
Combined result of both transactions
= $100-27
=$73 (profit)
So f(x)=x+10 lets say
so if you put something into the function lets say 5 then the function will do something to it and give you an answer so if you put in 5 for x you would get 5+10 or 15
a function of a function
lets say
f(x)=2x-9
g(x)=7x+2
(g(x) is just another function represented by g instead of f)
so if you wanted to put g(x) as x into f(x) and put x in g(x) to 3
then f(g(x))=2(7x+2)-9 or f(g(3))=2(7*3+2)-9=2(23)-9=37
