Answer 1

Answer:

d. 180 gallons

Step-by-step explanation:

18/4= 4.5 ( to find how many 4 minutes are in the 18)

4.5*40= 180 ( the question asked for the maximum amount of water (40) we      multiply to find how many gallons)

Answer 2

Answer:

  d. 180 gallons of water

Step-by-step explanation:

The maximum rate appears to be (40 gallons)/(4 minutes) = 10 gallons per minute. Then an 18-minute shower will use ...

  (18 min)(10 gal/min) = 180 gallons
