Company S produces two kinds of stereos: basic and deluxe. Of the stereos produced by Company S last month, 2/3 were basic and the rest were deluxe. If it takes 7/5 as many hours to produce a deluxe stereo as it does to produce a basic stereo, then the number of hours it took to produce the deluxe stereos last month was what fraction of the total number of hours it took to produce all the stereos

7/17

Explanation:

For easier calculation , let us represent the total number of stereo produced with a figure that can easily be divide into 3 .

Let us use 21 as the total number of stereo produced.

Basic stereo = 2/3 * 21 = 14

Deluxe stereo = (1- 2/3)*21 = 7

Now , if it takes 7/5 as many hours to produce a deluxe stereo to produce a basic stereo.

Let us assume that it took 2 hours to produce each  deluxe stereo, then each basic stereo was produced in 7/5 *2  = 14/10.

Total hours used to produce basic stereo = 14 *14/10 = 19.6. approximately 20

Total hours used to produce deluxe stereo = 2*7 = 14

Total number of hours for all stereo = 20+14 = 34

fraction of delute stereo hours to total stereo hours = 14 / 34 = 7/17

1   all nations face the problem of scarcity because there are limited resources and unlimited wants. nations do not have enough factors of production to produce everything that their population wants. entrepreneurial resources initiate businesses to make new goods and services; labor resources produce goods and services.

2 there are four factors of production: natural resources, labor resources, capital resources, and entrepreneurial resources. natural resources are raw materials from nature that are used to produce goods. trees, water, and grains are natural resources. some natural resources, such as wheat and cattle, are renewable
