Go mows lawns for 25 each he already has 260 in his bank account but is trying to save 900 how many lawns will he need to mow to reach his goal

To reach his goal of saving $900, he needs to earn an additional amount of money which is given by:

Additional amount = Goal - Current balance
Additional amount = $900 - $260 = $640

Since he earns $25 for mowing one lawn, the number of lawns he needs to mow is:

Number of lawns = Additional amount / Earnings per lawn
Number of lawns = $640 / $25 = 25.6

However, since he cannot mow a fraction of a lawn, he will need to round up the number of lawns to the next whole number. Therefore, he will need to mow a minimum of 26 lawns to reach his goal.
