A charger costs $6. How much would you need to pay after 10% sales tax has been applied?

$6.60

Step-by-step explanation:

A sales tax is a consumption tax imposed by the government, in other words, an extra amount you have to pay for the government.

In this problem, a $6 charger has a 10% sales tax, meaning that an extra 10% of the $6 will be payed.

Let's find the sales tax:

10% of 6 = .60

Add the sales tax to the chargers cost ($6):

$6 + 0.60 = $6.60

The total cost that will be payed, after the sales tax is $6.60

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
