Answer:
16 gallons
Step-by-step explanation:
Consumption
Since Monday and Tuesday are two days and each day, it's estimated that the consumption was 2 gallons hence to get the actual consumption for the two days
Monday and Tuesday= 2*2= 4 gallons
Wednesday to Saturday has 4 days and each day, the consumption was 3 gallons hence total consumption is also given as a product of the days and the daily consumption on average. Therefore,
Wednesday to Saturday= 3*4=12 gallons (We consider Wednesday, Thursday, Friday and Saturday)
To get the total consumption, we add respective consumption.
Total=4+12=16 gallons
