Question

Amy has $1,000 in a savings account at the beginning of the fall. She wants to have at least $500 in the account by the end of the fall. She withdraws $100 a week for living expenses. Write an inequality for the number of weeks Amy can withdraw money, and solve.

Answer 1

Amy starts out with $1000. Each week, she removes $100.
This can be expressed by: S=1000-100w, where S is the amount in her savings account, and w is the number of weeks that have passed.
Amy wants to have at least 500 dollars in her savings
