Final answer:
Gerald did not find any days where the sulfur content in the tires exceeded the 4% limit.
Step-by-step explanation:
Sulfur Content Problem in Rubber Tires
Gerald, the chemical engineer, has been tasked with solving a sulfur content issue in the manufacture of rubber tires. To determine the percentage of sulfur in the tires, Gerald monitored the sulfur content for 100 days. The number of days where the sulfur content exceeded the 4% limit can be calculated as follows:
Let's assume that on each of the 100 days, Gerald measured the sulfur content and found it to be below the limit. Therefore, the number of days that violated the 4% limit would be 0.
