Dinner at your favorite restaurant cost $64.50 with tax for you and your family. you give the waiter $75 to pay the bill and a tip. what is the approximate percentage of the tip?

20%

Step-by-step explanation:

move decimal multiply by 2

16%

Step-by-step explanation:

Cost of the dinner including taxes = $64.50

Amount paid by you = $75

So, the tip given to the waiter = 75 - 64.50 = 10.50

Now,

We need to find out the percentage of the tip paid on the bill.

i.e., How much percent of 64.50 is 10.50

64.50 ——- 10.50

100    ——- ?

Cross multiplying;

(100 x 10.50)/64.50

= 16.27% ~ 16%

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
