Answer:
B. 123
Explanation:
Let x be the total number of the tents for sale at the outdoor store.
We are told that 27 of tents for sale at an outdoors store are green. This represents 18% of all the tents in the store.
To find the total number of tents, we need to figure out x such that 18% of x equals 27.
![(18)/(100)x=27](https://img.qammunity.org/2020/formulas/mathematics/college/rreitlys97itihsgzcfy00p8dsdtzyla6z.png)
![0.18x=27](https://img.qammunity.org/2020/formulas/mathematics/college/q3ysmvrws5fnsmvo46w5tytx1rwm289olf.png)
Upon dividing both sides of equation by 0.18 we will get,
![(0.18x)/(0.18)=(27)/(0.18)](https://img.qammunity.org/2020/formulas/mathematics/college/f5cimk41on3l6drnqv79att1h8dsto9sav.png)
![x=150](https://img.qammunity.org/2020/formulas/mathematics/college/2kvhkrrkvk9ajfgp826ksmg0plyhnzpaa2.png)
Let us subtract the number of green tents from total number of tents to find the number of tents that are not green.
![\text{The number of tents that are not green}=150-27](https://img.qammunity.org/2020/formulas/mathematics/college/t1msgqyw5jr85lzp5vcba7s3mg0rev9rmz.png)
![\text{The number of tents that are not green}=123](https://img.qammunity.org/2020/formulas/mathematics/college/vg13oc70pyngft6i8n3rvz9skxdj3jstsv.png)
Therefore, 123 tents are not green and option B is the correct choice.
