What you will have to do is times 46.5 by 100 then with that answer you will divide that by 75 and you will get 62%
Answer:
312
Step-by-step explanation:
First we need to determine the width
A = l*w
6.2 * 10 ^3 = 1.55 * 10 ^2 * w
Divide each side by 1.55 * 10 ^2
6.2 ^ 10 ^3 /1.55 * 10 ^2 = 1.55 * 10 ^2 * w / 1.55 * 10 ^2
Changing from scientific notation to standard
6200/155 = w
40 = w
Then we need to determine the perimeter
P = 2(l+w)
P = 2( 155+40)
P =2( 195)
P = 390
Now multiply by the price
390 *.80
312
So you are going to pay $20 and then a 15% tip on top of the 20.
And the 15% tip is 15% of $20.
To do less work, you can basically do 115% of 20 to find out the total cost instead of doing 15% of 20 and then adding that to 20.
Saying that x is the final price to pay, and converting the percents to fractions we get:

Simplify that:

And simplifying that further, you get the final answer as:

So you have to pay $23 after the tip :)
