Answer:
16 and ½gallon
Step-by-step explanation:
To find out how much soap is needed to fill up the dispenser 6 times, you can multiply the capacity of the dispenser by the number of times you want to fill it:
\[2\frac{5}{8} \text{ gallons} \times 6 = 16\frac{1}{2} \text{ gallons}\]
So, you would need 16 and 1/2 gallons of liquid soap to fill up the dispenser 6 times.
