Answer:
<u>The correct answer is that Zack used 2 7/8 gallons to water his garden on the fifth week.</u>
Step-by-step explanation:
Let's find out the pattern Zack is using to water his garden, this way:
First week = 1 3/8 gallons of water
Second week = 1 3/4 gallons of water = 1 3/8 + 3/8 = 1 6/8 = 1 3/4
Third week = 2 1/8 gallons of water = 1 3/4 + 3/8 = 1 6/8 + 3/8 = 2 1/8
The constant of adding every week is 3/8 gallons, therefore,
Fourth week = 2 1/8 + 3/8 = 2 4/8 = 2 1/2 gallons of water
Fifth week = 2 1/2 + 3/8 = 2 4/8 + 3/8 = 2 7/8 gallons of water
<u>The correct answer is that Zack used 2 7/8 gallons to water his garden on the fifth week.</u>
