Answer:
4th option 0,5,10,15
Step-by-step explanation:
Let's check if the first choice is geometric.
2*3 = 6. is 6*3 = 18, yes! is 18*3 = 54. Yep! its geometric
the second option multiplies by -2, it is geometric
the third option multiplies by 1/5, it is geometric
The fourth option does not multiply by anything common, it is Not geometric
Turn it into a ratio.
The beginning ratio is 3:20, because there are 3 counselors for every 20 campers.
Then, you do x:120, x representing the number of counselors.
You have to multipy 20 by 6 to get 120, so you multiply 3 by 6 to get x.
Therefore, there are 18 counselors if there are 120 campers.
Answer:
20 * 19.52 = 390.40
