Geo’s lawns for $25 each. He already has $250 in his bank account but he’s trying to save $900. How many loans will he need to mow to reach his goal?

Geo needs to save $900 and already has $250, so he still needs to save an additional 900 - 250 = $<<900-250=650>>650.

Thus, Geo needs to mow 650 / 25 = <<650/25=26>>26 lawns to reach his goal. Answer: \boxed{26}.

To find out how many lawns Geo needs to mow, we can determine the difference between his savings goal and the money he already has.

The amount Geo needs to save is $900, and he already has $250 in his bank account. So the difference is:

$900 - $250 = $650

Now, we divide the remaining amount ($650) by the price of each lawn ($25) to find out how many lawns Geo needs to mow:

$650 / $25 = 26

Therefore, Geo will need to mow 26 lawns to reach his goal of saving $900.

To find out how many lawns Geo needs to mow to reach his goal, we need to calculate the difference between his goal and his current bank balance, and then divide that by the amount he earns per lawn.

Let's go step by step:

1. Subtract Geo's current bank balance ($250) from his goal savings ($900): $900 - $250 = $650.

2. Divide the remaining amount Geo needs to save ($650) by the price he earns per lawn ($25): $650 ÷ $25 = 26.

Therefore, Geo will need to mow 26 lawns to reach his savings goal of $900.
