A company wants to purchase two types of lightbulbs, CFL (compact fluorescent) and LED (light emitting diode). The cost of each CFL bulb is $2, and the cost of each LED bulb is $20.
The company must purchase a total of 800 lightbulbs, must spend at most $5,000 on the lightbulbs, and wants to
purchase as many LED bulbs as possible.
Let L represent the number of LED lightbulbs purchased, and C represent the number of CFL lightbulbs purchased.
Which of the following systems models the situation described?
2C + 20L - 800
C+L < 5,000
B
20C + 2L = 800
C + L < 5,000
20 + 20L < 5,000
C + L = 800
200 + 2L < 5,000
C+L - 800
