Answer:
The most number of layers he can afford is 2
Step-by-step explanation:
We automatically have a fee of 17 so we know we have 13 dollars remaining. Using this information, we know that one layer is 5 dollars which means we can get 2 layers which is equal to 10 dollars which turns our total fee to $27. Hope this helps!
First off you have the starting cost (C). C=$17 each layer is $5, so that becomes 5x. the equation will be $17+5x=30 hope this helped !! :)
