𝑤+45=315

The correct equation to determine how much Devon needs to save in order to have $315 in his savings account is 𝑤+45=315.

To understand why, let's break down the equation:

𝑤 represents the amount of money Devon needs to save.
"+45" represents the $45 he already has in his account.
=315 represents the total amount Devon wants to have in his account.

By adding the $45 Devon already has to the amount he needs to save (𝑤), the sum should be equal to $315.

Therefore, 𝑤+45=315 is the equation that can be used to determine how much Devon needs to save.
