Answer: 2.81 per hour
Step-by-step explanation:
Average monthly productivity = (January productivity + February productivity + March productivity + April productivity) / 4
January productivity:
= Units produced / ( Hours per machine * Number of machines )
= 2,250 / ( 318 * 2 )
= 3.537
February productivity:
= 1,750/ ( 194 * 4 )
= 2.255
March productivity:
= 2,750 / ( 393 * 3 )
= 2.332
April productivity:
= 2,950/ ( 315 * 3)
= 3.121
Average monthly productivity = (3.537 + 2.255 + 2.332 + 3.121)/ 4
= 2.81 per hour
