b- if each gallon cost $24.80, find the cost of the project?

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.

answer: approximately 206 bones

i hope this u out a branlist and a would be greatly appreciated :
