Help please!!!!

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.

s(x)=85 piggy bank

a(x)=10(x-1) allowance

he currently has the money in his piggy bank which is 85
then he gains 10(x-1) for every week that x is, 
so you know that on the first week he is doing laundry he has the allowance a(1)=0
but you already have 85 in your piggy bank so your new function will give you 0+85
meaning 85 is your starting case so you always have 85 from the start

therefore you get a new function s(x)+a(X) which we will label f(x)
so f(x)=s(x)+a(x)
f(x)=85+ 10(x-1)
