I want to say the third option but dont trust my opinion
F(b)=7b+8
you just need to change the x variable. make y into f(x) or in this case f(b)
You take 45,000 divided by .15= 30,000
30,000 it your answer
Hope this helps

Well first of all if I had a multiplication question such as 12,000×1000 of course you would know it would be 12,000 well you would always use your place value chart saying ones tens hundreds thousands and thousands and hundreds
