Maynard · Answer 1

The equation is - 20x + 509 = 220

Step-by-step explanation:

Write the equation down. Then subtract 509 from both sides, which will equal - 289. You should have - 20x = - 289. Next, divide both sides by - 20, and you will get 14.45 as your final answer. So, it will take about 14 weeks for Heather to have a balance of 220.
