I don’t understand this Help please ASAP!!!

Answer:
[tex]4t + 15j > 800[/tex]
Please read explanation below as well.
Step-by-step explanation:
We know the following information:
- The number of T-shirts is represented by the variable [tex]t[/tex]. Each T-shirt costs $4. The total cost depending on the number of T-shirts can be represented by [tex]4t[/tex].
- The number of jeans is represented by the variable [tex]j[/tex]. Each pair of jeans costs $15. The total cost depending on the number of jeans can be represented by [tex]15j[/tex].
- The stores want to sell more than $800. This idea is represented mathematically by writing [tex]>800[/tex].
The total cost of jeans and T-shirts depending on the quantities of each of them is represented as a sum: [tex]4t + 15j[/tex]. This total cost has to be more than $800: [tex]4t + 15j > 800[/tex].
