Answer 1

Hi!

I will put the key parts of this word problem in bold. 

Tina had $640 in her bank account. When she took out d dollars, her balance was $460. 

So, try to write an equation from that information. 

$640 took out d makes $460
$640 - d = $460

The answer is B. $640 - d = $460

Hope this helps! :)
