What inequality is shown on the graph? Write your inequality with the variable coming first. Use the letter m for the variable. Write your answer using a decimal number. Number line from 16 to 32. open circle on 25.6 going to positive
The inequality shown on the graph is:
m > 25.6
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.
Let w represent the number of weeks Lily will need to save before having at least $300.
The amount of money Lily saves after w weeks can be represented by the inequality:
40 + 65w ≥ 300
The solutions to this inequality represent the number of weeks Lily will need to save in order to have at least $300.
How many weeks would she have to save to get 300?
To find out how many weeks Lily would have to save to have at least $300, we can solve the inequality:
40 + 65w ≥ 300
Subtract 40 from both sides:
65w ≥ 260
Divide both sides by 65:
w ≥ 4
Therefore, Lily would need to save for at least 4 weeks in order to have $300 or more.
