Four volunteer groups recorded their summer vegetable harvests: Group A harvested 150 pounds, Group B harvested 175 pounds, Group C harvested 200 pounds, and Group D harvested 225 pounds. If a new group, Group E, joins and harvests 50 pounds, what is the new average yield per group?
Show answer & explanation
Answer: A. 160 pounds
Total harvest = 150 + 175 + 200 + 225 + 50 = 800 pounds. Across 5 groups, the new average is 800 / 5 = 160 pounds.
Step-by-step Derivation:
Step 1: Sum of harvests = 150 + 175 + 200 + 225 + 50 = 800 pounds.
Step 2: Total number of groups = 5.
Step 3: New average = 800 / 5 = 160 pounds.
