We know that 80a + 70w ≤ 7500 because Ms. Robinson cant spend more than 7500, so the answer must be A or D.
We also know that a + w ≥ 100 because Ms. Robinson must buy at least 100 chairs.
This leaves our answer to be A
D, because there might be values higher than 120, because the data points range from 0 - 200.
Answer:
The number w is 4,000
Step-by-step explanation:
Let
w ------> the number
we know that
36 is 0.9% of number w
w represent the 100%
so
using proportion
Find out the number w
therefore
The number w is 4,000
If you distribute -4 through (5k-7), it equals -20k + 28. Then put on the other -2k on that side of the equals sign and you should have -22k + 28 = -2(9k+5) Then you need to distribute -2 through (9k+5) which equals -18k - 10. You then should have -22k+28=-18k-10. Add 22k to both sides to cancel it out, then you should have 28=4k-10. Add 10 to both sides to get the 4k by itself, which will be 38=4k, then divide both sides by 4 to get k by itself. 38/4 = 19/2. k = 19/2
