Arthur has decided to start saving for a new computer. His money is currently in a piggy bank at home, modeled by the function s(x) = 85. He was told that he could do the laundry for the house and his allowance would be a(x) = 10(x − 1), where x is measured in weeks. Explain to Arthur how he can create a function that combines the two, and describe any simplification that can be done.

Question

anonymous · Answer

I might have the answer, but i'm not sure if it's right because it was so simple. f(x)=85+ 10(x-1)

anonymous · Answer

^ That is correct

anonymous · Answer

Yes, but i'm not sure how to simplify it any further other than  adding terms and then reverse distribution. f(x)=5(15+2x)

anonymous · Answer

Actually I think that's right, nevermind
