Answer 4

you have 10b =70 and you know that you add on 5$ per extra box
this means you will have an equation in the form of C=ab+c


now we know that we start with 70, so our c=70
C=ab+70

next we know for each extra box b, we will pay 5$ so we get an expresion of 5b

therefore your answer will be
C=70+5b

Answer 5

the minimum is 10 boxes so you must pay 70 + any extra at 5/box
so 70 +5b is the answer
