The average rate change is 11
You can separate them so 6-4 and 1/2 - 1/7
6-4=2
1/2-1/7 you need to find a common denominator- 14
As you need to multiply 2 by 7 to get 14 you multiply the 1 by 7 to get 7/14. For the 1/7, you need to times the 7 by two to get 14 so you times the 1 by 2 to get 2/14.
So you get 7/14-2/14, because you have the same denominators you just subtract the top numbers and leave the bottom so you get 5/14. Add the 2 from earlier and your answer is 2 5/14
Answer:
There are 8 carnations in each bouquet.
Step-by-step explanation:
So, first, we have to figure out the total amount of flowers in one bouquet. To find that, we would do 150 flowers divided by 6 bouquets. That gives us 25 flowers in 1 bouquet. Next, we have to figure out how many carnations are there. To find that, we would first add 12 daises and 5 roses, which is 17 flowers. Since we already know there are 17 flowers that aren't carnations, we would subtract 17 flowers from 25 flowers. That gives us 8. That means that there are 8 carnations :)
65 bought 3 or more.
950x0.82=779
779-528=251
251-186=65
Final answer: 65
