b. Every 24 minutes
Step-by-step explanation:
A neon sign blinks every 6 minutes, and another sign blinks every 8 minutes.
The first step is to:
Find and list multiples of each time each neon sign blinks.
This means, we find the Multiples of 6 and 8
Multiples of 6:
6, 12, 18, 24, 30, 36
Multiples of 8:
8, 16, 24, 32, 40
The first and common multiple of 6 and 8.
Therefore, the Least common multiple [LCM(6, 8) ] = 24
Hence, they often blink at the same time every 24 minutes.
Therefore, option b.Every 24 minutes is correct.

Answer:
$113.81
Step-by-step explanation:
Find the cost for one book:

Step-by-step explanation:
Answer: Ellen's house is farther away by 898 feet.
Step-by-step explanation:
Given: The distance between Haley's house and Ellen's house = 1.41 miles
We know that 1 mile = 5,280 feet
Then, 
The distance between Haley's house and Dirk's house = 6,547 feet
Clearly, 6,547<7,444.8
And 
Therefore, Ellen's house is farther away by 898 feet.
= 20y + 3y -4(-2y)
= 20y + 3y + 8y
= 31y
In short, Your Final Answer would be 31y
Hope this helps!
