Question

Lily is saving up to buy a cellphone. She needs to save at least $300 before she is able to buy the phone. Her grandfather gives her $40, and she earns $65 tutoring after school each week. Write an inequality for the number of weeks Lily will need to save to have at least $300, and describe the solutions.

Answer 1

Let's say the number of weeks Lily needs to save is represented by the variable "w".

Each week, Lily earns $65, and her grandfather gives her $40. In total, she has an income of 65w + 40.

To determine the number of weeks Lily needs to save to have at least $300, we can set up the following inequality:

65w + 40 ≥ 300

The solutions to this inequality represent the number of weeks Lily needs to save in order to have at least $300.

Answer 2

Fill in the blanks for the question I just asked you.
__x + __ ≥ __, where x is the number of weeks Lily will need to save. Lily must save for at least __ weeks to have at least $300.

Answer 3

65w + 40 ≥ 300
The solutions to this inequality represent the number of weeks Lily needs to save in order to have at least $300.

Lily must save for at least __ weeks to have at least $300.
