11. all services at the salon are 25% off today. maria decided to get a haircut that originally costs $22. a. what would her total bill be with the discount? b. now she needs to leave a 20% tip. how much should she leave?

A. $22 x .25 = $5.50

$22 - $5.50 = $16.50

B. $16.50 x .20 = $3.30

So for part (A) you will look at the total amount of the haircut which is $22.00 and the discount of 0.25%.

The math there will be asking "what is 25 % of 22" (the answer is $5.50). You can also figure it out by doing 22.00 * 0.25 (this is will still come out to be $5.50). So the total bill with the discount will be ($16.50). How to get that is you will take $22.00 - $5.50 ($16.50 hair cut with the discount).

Now she is going to leave a tip, now remember, her current total is $16.50 because she got a discount. So you will follow the same math, 20% of $16.50 is $3.30. In this case you will add, $16.50 + $3.30 = $19.80. So her final amount is going to be $19.80.

A - $16.50

B - $19.80

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

60.9774

step-by-step explanation:

because when you add 47.6 plus 7.32 equals 54.92

and when you add .0574 + 6= 6.0574

and when you add 54.92 and 6.0574 you get the answer of 60.9774.
