Question

An electronics company makes TVs. When testing the new TVs, the company finds that about 2 out of every 25 TVs do not work. On one day, 18 TVs did not work. About how many new TVs were made that day?

a. 34
b. 41
c. 162
d. 225

Answer 1

To find the total number of new TVs made, a proportion of faulty units to total units produced is used. The correct answer based on the proportion of 2 faulty TVs out of every 25 is 225 TVs produced. Therefore, the correct option is d. 225.

Step-by-step explanation:

The question involves finding the total number of new TVs made based on the proportion of TVs that do not work. If 2 out of every 25 TVs do not work, and on one day 18 TVs did not work, we can set up a proportion to find the total number of TVs made that day:

2/25 = 18/x

To solve for x, we cross-multiply and get 2x = 18 × 25. Therefore, x = (18 × 25) / 2, which simplifies to x = 450 / 2, giving us x = 225.

The total number of new TVs made that day is 225. So the correct answer is d. 225.
