Question

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.

You can write ≥ like this >=

Answer 1

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.
