Question

Katrina drinks 0.5 gallons of water per day. Which expression shows how to find the number of cups of water she drinks in a week

Answer 1

well there is 16 cups in the a gallon so every day she drinks 8 cups lets make an equation using x for days passed and y the total cups drank
y=8x

Answer 2

The expression is as follows: x = 8y

Step-by-step explanation:

1 gallon is 16 cups, therefore 0.5 gallons is 8 cups. If we denote x as the cups of water and "y" are the days, therefore, the equation is:

x = 8y

If y = 7, which is 7 days a week, therefore, the number of water rates you drink will be equal to:

x = 8x7 = 56 cups
