Answer:

20 TV need to be sold to qualify for the trip.

Step-by-step explanation:

Given: Sale price of each TV is $250

Sales target to qualify for trip is $5000.

As given, T represent TV sold.

Now, finding the number of TV sold to qualify for the trip.

Forming an inequality for the number of TV sold to qualify for trip.

We know, Total amount of TV sold= $Selling\ price\ of\ each\ TV \times Number\ of\ TV\ sold$

∴ To qualify for trip: $250T\geq 5000$

solving it by dividing both side by 250

∴ $T\geq \frac{5000}{250}$

$T\geq 20\ TV$

Hence, Angelica need to sell minimum 20 TV to qualify for the trip.
