Respuesta :

Let L represent the number of LED lightbulbs purchased

Let C represent the number of CFL lightbulbs purchased

The cost for L = $20

The cost for C = $2

Total lightbulbs = 800

Spend for the company: at most $5000, this is ≤ $5000

Given the situation, the following equations can be obtained:

[tex]\begin{gathered} 2C+20L\leq5000 \\ and \\ C+L=800 \end{gathered}[/tex]

Answer: D.
