Answer:5x + 30 ≥ 90
Step-by-step explanation:Sure! Here's a real-world problem that can be represented by the inequality 5x + 30 ≥ 90:
Problem: Emma is saving money to buy a new bicycle. She currently has $30 and saves $5 each week. Emma wants to make sure she has enough money to buy the bicycle when the total amount saved is at least $90. How many weeks will it take for Emma to save enough money?
Solution:
Let x represent the number of weeks it takes for Emma to save enough money. Since she saves $5 each week, the total amount saved after x weeks can be represented by 5x.
We can write the inequality as follows:
5x + 30 ≥ 90
This inequality states that the total amount saved, represented by 5x plus the initial amount of $30, must be greater than or equal to $90.
By solving the inequality, we can determine the minimum number of weeks it will take for Emma to save enough money to buy the bicycle.
