Quizplus · Accepted Answer

To find the number of defective computers, we can use the formula:

Number of defective computers = (Percentage of defective computers / 100) x Total number of computers

Plugging in the given values, we get:

Number of defective computers = (1.98 / 100) x 2680
Number of defective computers = 53.04

Since we cannot have a fractional number of defective computers, we round up to the nearest whole number, giving us:

Number of defective computers = 54

Therefore, the best choice is C (53) as it is the closest number to our calculated value.
