Heather has $500 in her savings account. She withdraws $20 per week for gas. Write the equation heather can use to find out how many weeks it will take her to have a balance of $220

500 - 20x = 220

500 - 20x = 220

I hate math with a passion and always will.

500 - 20x = 220

This is because she has 500 dollars in her account and withdraws means to take something out which is negative so we subtract 500 - 20x. X represents the amount of money she withdraws per week for the gas and she had a balance of 220 dollars.

To write the equation, let's first figure out how much Heather's savings will decrease each week. Since she withdraws $20 per week, her savings will decrease by $20 every time.

Let's denote the number of weeks as 'w'. At the beginning, Heather has $500 in her account. For each week, she will withdraw $20, so her balance after 'w' weeks will be:

$500 - $20w

To find out how many weeks it will take her to have a balance of $220, we can set up an equation:

$500 - $20w = $220

Now, we can solve this equation to find the value of 'w'.
