Respuesta :

Answer:

14 necklaces.

Step-by-step explanation:

The question asks for x where x is necklaces sold, p is profit and t is total profit, that would be x * p = t

Here we're looking for x so we rearange it to x = t / p

280 / 20 = 28 / 2 = 14 necklaces

Inequalities are used to represent unequal expressions

The inequality that represents the number of necklaces is 20x <= 280

The profit per item is $20.

Let the number of items be x.

So, the profit on x items is:

Profit= 20x

At least $280 profit means: greater than or equal to 280.

So, we have:

Profit <= 280

Substitute 20x for Profit

20x <= 280

Hence, the inequality is 20x <= 280
