n ultra-low flush toilet uses 1.6 gallons every time it is flushed. What is the pattern that describes the total water used after n flushes? How many gallons have been used after 10 flashes?

Question

Let n = number of flushes
1.6n is the number of gallons used in n flushes.
y = 1.6n is the function (pattern) that shows how much water is used (y) for n number of flushes.

For 10 flushes, let n = 10. Plug in 10 for n in the equation (pattern) and calculate y:

y = 1.6 * 10
