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 =)
124.95 + 7% tax = 124.95 * 1.07 = $133.70
Plus $10 = $143.70 <--- answer to part 1
Part 2
143.70 / 15 = 9.58
it will take him 10 weeks to save enough to purchase it.
Only C and D....................
First, let's input "a" and "b" into the equation:
(Don't forget to put brackets around the inputted numbers to show you are inputting "a" and "b")
<span>4 ÷ a × b = </span>4 ÷ (444) x (213)
Now we can solve!
= 1.918
= ~ 2
Hope this helps!
