Let x represent the number of weeks it will take for Sarah to save enough money to buy the bicycle.
The inequality is:
30x + 80 >= 200
Solving for x:
30x >= 120
x >= 4
It will take Sarah at least 4 weeks to save enough money to buy the bicycle.
Sarah wants to buy a bicycle that costs at least $200. She has $80, and she earns $30 from her part-time job each week.
Solve the inequality.
Note:
Make sure to write the inequality so the x comes first.
You can write ≤ like this <=
You can write ≥ like this >=
