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.
So he starts saving for a computer. He already has s(x)=85 and by doing the laundary for the house he can also get a(x) = 10(x-1) = 10x-10 You can combine a(x) + s(x) which would equal all the money he is saving towards his computer. So combine 10x-10 and 85 and what do you get?
so thats the final answer?
That would be indeed. Because you combine both of his saving values, which is what we are trying to do.
okay thanks!! i have 1 more. new post
