Final answer:
To estimate the number of new TVs made on a day, we can set up a proportion using the information given. About 225 new TVs were made on that day.
Step-by-step explanation:
To estimate the number of new TVs made on a day, we can set up a proportion using the information given. We know that about 2 out of every 25 TVs do not work, so the ratio of defective TVs to total TVs is 2/25. We can set up a proportion with this ratio and the number of defective TVs given (18) and solve for the total number of TVs made on that day.
2/25 = 18/x
Cross-multiplying gives us 2x = 25 * 18, and dividing both sides by 2 gives us x = (25 * 18)/2 = 225.
Therefore, about 225 new TVs were made on that day.s
