Answer:
Step-by-step explanation:
Total number of toll-free area codes = 6
A complete number will be of the form:
800-abc-defg
Where abcdefg can be any 7 numbers from 0 to 9. This holds true for all the 6 area codes.
Finding the possible toll free numbers for one area code and multiplying that by 6 will give use the total number of toll free numbers for all 6 area codes.
Considering: 800-abc-defg
The first number "a" can take any digit from 0 to 9. So there are 10 possibilities for this place. Similarly, the second number can take any digit from 0 to 9, so there are 10 possibilities for this place as well and same goes for all the 7 numbers.
Since, there are 10 possibilities for each of the 7 places, according to the fundamental principle of counting, the total possible toll free numbers for one area code would be:
Possible toll free numbers for 1 area code = 10 x 10 x 10 x 10 x 10 x 10 x 10 = 
Since, there are 6 toll-free are codes in total, the total number of toll-free numbers for all 6 area codes =

Answer:
4 yellow rosebushes
Step-by-step explanation:
Givens(What the question tells us):
m = 3(There are 3 multicolored bushes)
r + y + p = 15 - m( total red bushes plus total yellow bushes plus total pink bushes equals 15 - the amount of multicolored bushes)
r = y = p (total red bushes equals total yellow bushes which also equals total pink bushes)
Since we know m =3 we can substitute m for 3 in the second equation:
r + y + p = 15 - 3.
r + y + p = 12
Now since r, y, and p are equal we can divide the total amount left (12) by the 3 kinds of roses left to get our answer:
12/ 3 = 4 red, 4 yellow, and 4 pink
Since we are solving for the amount of yellow the answer is:
4 yellow rosebushes
