There is a family of 4. They use 225gals of water a week and 35gal a day for bathing, if they decreased it by 1/5.how much water will they save?
they would save 94 gallons.
If they use 35gal/day= 245 gal for bathing in a week.
225+245= 470 gallons a week. if they reduced it by 1/5 just multiply the 470 by (1/5)= 94gallons.

8 * 4 = ?
To calculate how much water the family will save, we first need to find out how much water they use in a week and then determine how much they will save by reducing it by 1/5.
Step 1: Calculate the total water used in a week.
Given that the family uses 35 gallons of water per day for bathing, we can multiply this by 7 (the number of days in a week) to calculate the total water used for bathing in a week.
35 gallons/day x 7 days/week = 245 gallons/week
Step 2: Calculate the total water used in a week for all purposes.
Since the question doesn't provide information about other water usage, we can assume that the additional water used in a week (besides bathing) is 225 - 245 = -20 gallons. However, a negative value doesn't make sense in this context, so we'll assume that the family uses zero additional water in a week for other purposes.
Step 3: Calculate the amount of water saved by reducing water consumption by 1/5.
To find out the amount of water saved, we need to calculate 1/5 of the total water used in a week for bathing.
1/5 x 245 gallons = 49 gallons
Therefore, the family will save 49 gallons of water by reducing their water consumption by 1/5.
