x = 2 x 45 is the equation. There will be only positive numbers

Step-by-step explanation:

An equation involves an '=' sign where the left side equals the right side.

To form an equation, first write down the known and unknown data.

1. Number of paychecks: 2

2. Amount of each paycheck: $45

3. Amount of total money deposited = x

<u>EQUATION:</u>

Amount of total money deposited = Number of paychecks x Amount of each paycheck

x = 2 x 45

x = $90

Therefore, the total money deposited would be $90.

There are positive numbers in this because a paycheck has to be $\geq 1$ and negative amount cannot be deposited in a bank; there has to be some amount.
