$60 for 2 hours and $100 in total for 2 hours of work and the service fee
Add 1/4 to both sides to get T=-2/4
To find this answer, we must first find the percentage of batteries that are defective. We can do this by dividing 3 by 500.
3 / 500 = 0.006
So our percentage of defective batteries is 0.6%.
Now, to find out how many defective batteries would be in a batch of 12000, we just need to multiply the constant (percentage of defective batteries) by the amount in the new batch.
12000 * 0.006 = 72
In a shipment of 12,000 batteries, 72 will be defective, so the correct answer choice would be B.
Hope that helped =)
