Question

Heather has 509 in her savings account.She withdraws 20 per week for gas.Write an equation Heather can use to see how many weeks it will take her to have a balance of 220.

Answer 1

Answer:

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.
