XYZ Inc Produces Two Types of Printers-Regular and High-Speed $X_{1}$ Be the Number of Units of Regular Produced Per Month

XYZ Inc. produces two types of printers-regular and high-speed. Regular uses 2 units of recycled plastic per unit, and high-speed uses 1 unit of recycled plastic per unit of production. The total amount of recycled plastic available per month is 5,000. A critical machine is needed to manufacture the printers. Each unit of regular requires 5 units of time in this machine, and each unit of high-speed requires 3 units of time. The total time available in this machine per month is 10,000 units. Let $X_{1}$ be the number of units of regular produced per month and $X_{2}$ the number of units of high-speed produced per month. The appropriate constraint/s will be

A) $2 X_{1}+X_{2}=5000$
B) $2 X_{1}+X_{2} \leq 5000$
C) $5 X_{1}+3 X_{2} \leq 10000$
D) A and C
E) B and C
