Situation A
Maria opened a new savings
account with an initial deposit of
$100. She deposits $75 into this
savings account every
two-weeks. What equation can
be used to represent Maria's
account balance, a, after she has
completed d deposits?

The equation a = 100 + 75d represents Maria's  account balance.

Step-by-step explanation:

Given that,

You need to find the equation to represent Maria's  account balance, a after she has  completed d deposits.

Therefore, the equation for the total account balance can be framed as the sum of the initial deposit and amount deposited after that.

To find the amount that was deposited after the initial deposit :

⇒ $75 × number of times Maria deposited.

⇒ 75 × d

The equation is written as,

⇒ a = 100 + 75d

Hence the equation a = 100 + 75d represents Maria's  account balance.
