Since she has a base amount of $500, that will be your y-intercept. 20 is going to be your slope, and since she's withdrawing it, it will be -20. Here's how the equation would be set up (in y = mx + b):
-20x + 500 = 220
*Subtract 500 from both sides*
-20x = -280
*Divide both sides by -20*
x = 14.
Therefore, it will take 14 weeks.
