Answer: $22
Step-by-step explanation:
First we calculate for the sale price.
We have to find how much is 60% of 50.
We do this by:

This equals 30.
We now subtract the 30 from the 50 to get our sale price.

The sale price is $20.
Now we have to add a 10% sales tax. This is done by multiply the percentage and adding 1 to it like this.

This equals 1.1
This is what we will multiply the $20 by.

The total cost is $22.
Now, a whole, will be 15/15 or 1 whole.
now, the sprinkler does 1/15 of the lawn in 1/3 of an hour, how long will it be to do the whole 15/15?
