Answer 1

Answer:

$a=180-2.50d$

Step-by-step explanation:

If Penny starts with a balance of $180, and $a$ represents the account left in her account after $d$ days. we can start modeling an incomplete equation:

$a=180$

We are then told that she spends $2.50 each ($d$) day. This can be represented as:

$2.50d$

Let's now include the expression into the incomplete equation. Remember that since she is spending, the $2.50d$ will be subtracted from her balance of $180:

$a=180-2.50d$

Answer 2

D=180-2.50x I think.
