Answer 1

Over the first 12 days of the month, Harmie used 2.52 CCF of water. If she continues at this rate, how many CCF's of water will she use at the end of 30 days?​

we have that

12 days ------> 2.52 CCF

so

Applying proportion

Find out how many CCF's of water will she use at the end of 30 days

2.52/12=x/30

solve for x

x=(2.52/12)*30

x=6.3 CCF

answer is 6.3 CCF
