George has $75 saved. He know he can make $20 for each lawn (l) he mows. He would like his savings account balance to be at least $500 by the end of the month.

How many lawns will George have to mow to reach his savings goal?

1 answer

We can start by subtracting George's current savings from his goal savings to find out how much more money he needs to make:

$500 - $75 = $425

We know George can make $20 for each lawn he mows, so we can set up an equation to represent the situation:

20l = 425

To solve for l, we can divide both sides by 20:

l = 21.25

Since George can't mow a fraction of a lawn, we can round up to the nearest integer:

l = 22

Therefore, George will need to mow 22 lawns to reach his savings goal of $500 by the end of the month.
