In a town, there are 170 teenagers that own portable media players. This is at least 2/3 of all the teenagers in the town. What is the maximum number of teenagers who live in the town?

(2/3)x >= 170

255

To find the maximum number of teenagers who live in the town, we can use the fact that 170 teenagers owning portable media players is at least 2/3 of all the teenagers in the town.

Let's assume the total number of teenagers in the town is "x".

According to the given information, 170 is at least 2/3 of x. Mathematically, we can write this as:

170 ≥ (2/3)x

To find the maximum value of x, we need to find the highest value that satisfies this inequality.

To isolate x, we can multiply both sides of the inequality by 3/2:

(3/2) * 170 ≥ (3/2) * (2/3) * x

255 ≥ x

Therefore, the maximum number of teenagers who could live in the town is 255.
