Answer:
40 workers
Step-by-step explanation:
Let's calculate the number of workers needed separately for protractors and calculators.
For protractors:
To make 250 protractors per hour, each worker can make 10 protractors per hour.
250 ÷ 10 = 25 workers
For calculators:
To make 60 calculators per hour, each worker can make 4 calculators per hour.
60 ÷ 4 = 15 workers
Then we take
25 + 15 = 40 workers
So, the company will need a total of 40 workers to make the exact amount of products every hour.
