Answer 1

Answer:

$y=3x+2\\\\where\ y\ is\ total\ expenditure\ and\ x\ is\ number\ of\ items.\ x\ can\ be\ any\ integer\ and\ 0\leq x\leq 4.$

Step-by-step explanation:

Let number of items$=x$

Let total expenditure$=y$

$cost\ of\ 1\ item=\ 3.00\\\\Cost\ of\ x\ items=cost\ of\ 1\ item\times x=3.00x\\\\Entrance\ fee=\ 2.00\\\\Total\ expenditure=Cost\ of\ items+Entrance\ fee\\\\y=3.00x+2.00\\\\y=3x+2$
