Paul has $78 in the bank and saves $30 each week. What is the initial value? Be sure to use negative signs if needed.

marin [14]

Answer:

The initial value is $78

Step-by-step explanation:

Given

$Base\ Amount = \$78$

$Additional = \$30$ (weekly)

Required

Determine the initial value

The initial value is the amount he has in its bank account before making his weekly savings.

From the question, we have that his initial balance is $78.

Hence, the initial value is $78

However, his weekly balance can be expressed as:

$Balance = Base\ Amount + Additional * number\ of weeks$

Represent number of weeks with x; So, we have:

$Balance = 78 + 30 * x$

$Balance = 78 + 30 x$
