1 point
30x + 80 ≥ 200
30x + 80 > 200
30x + 80 < 200
30x + 80 ≤ 200
80x + 30 ≥ 200
80x + 30 ≤ 200
80x + 30 < 200
80x + 30 > 200

Answer 1

30x + 80 ≥ 200

This is the correct inequality for the number of weeks Sarah will need to save to have enough money to buy the bicycle. The number of weeks, represented by x, needs to be multiplied by $30 earned each week and added to the initial $80 that Sarah has to be greater than or equal to $200.

The solutions for this inequality will give the minimum number of weeks Sarah needs to save up in order to have enough money to buy the bicycle, considering she can save exactly $30 each week.
