3) a cable company had 595 subscribers. the ratio of regular subscribers to premium
subscribers was 8: 9. how many regular subscribers did they have?

280

Step-by-step explanation:

We know that there are at least 8 regular subscribers and there are at least 9 premium subscribers. And we know it's in that ratio. So the best way to start this is to divide 595 by 8+9 to get the single unit amount of both subscribers:

595/17 = 35

So one unit of anything is at least 35. Now, since we're looking for regular subscribers, we'll multiply this value by 8:

35*8 = 280

So 280 is our answer!

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
