Ms griffin goes to dinner. she spends $12.89 on her meal and $1.99 on the drink with tax being 8%. she paid with a $50 bill how much change will she receive

Ms Griffin will receive the change of $33.93.

Step-by-step explanation:

Price of meal = $12.89

Price of Drink = $1.99

Total Money gave = $50

tax= 8%

We need to find how much change will she receive after paying the bill.

Total Money on dinner is equal to sum of Price of meal plus Price of drink

Hence equation can be framed as;

Total Money on dinner  =

Now Amount of tax paid  will be percentage of tax multiplied by total money on dinner.

Amount of tax paid =

Total billed amount = Total Money on dinner + Amount of tax paid =

Now amount of money she will receive back will be equal to Amount of money she paid minus Total billed amount.

Money she will receive back =

Hence, Ms Griffin will receive the change of $33.93.

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.
