Answer: the sales for the month must be greater than or equal to $6666.7
Step-by-step explanation:
Let x represent her sales for the month.
Liz earns a salary of $2,500 per month, plus a commission of 6% of her sales. If she makes sales worth $s for the month, then her commission for the month would be
6/100 × s = 0.06 × s = 0.06s
Her total income for a month would be
2500 + 0.06s
She wants to earn at least $2,900 this month.
Therefore, the inequality that represents the situation would be
2500 + 0.06s ≥ 2900
0.06s ≥ 2900 - 2500
0.06s ≥ 400
s ≥ 400/0.06
s ≥ 6666.7
Answer:
21
Step-by-step explanation:
Given,
- Number of red marble = 4
- number of green marble = 3
- number of transparent marble = 1
- number of yellow marble = 3
- number of orange marble = 3
Total number of marble except red and green = 3 +3+1
= 7
So, the total number of possible sets of five marbles such that none of them are green or red can be given by
![n\ =\ ^7C_5](https://tex.z-dn.net/?f=n%5C%20%3D%5C%20%5E7C_5)
![=\ \dfrac{7!}{(7-5)!.5!}](https://tex.z-dn.net/?f=%3D%5C%20%5Cdfrac%7B7%21%7D%7B%287-5%29%21.5%21%7D)
![=\ \dfrac{7!}{5!.2!}](https://tex.z-dn.net/?f=%3D%5C%20%5Cdfrac%7B7%21%7D%7B5%21.2%21%7D)
![=\ \dfrac{42}{2}](https://tex.z-dn.net/?f=%3D%5C%20%5Cdfrac%7B42%7D%7B2%7D)
= 21
So, the required number of possible sets are 21.
