22x0.0525 = 1.155
22 x 0.15 = 3.3 (tip)
22 + tax + tip = 26.46 (unless the tax is actually 11.55)

Answer:
The rectangle has a width of 18 inches and a height length of 8 inches.
Step-by-step explanation:
The perimeter of a rectangle is described by the equation:
![p = 2w + 2l](https://tex.z-dn.net/?f=p%20%3D%202w%20%2B%202l)
where <em>l</em> is width, <em>h</em> is height, and <em>p</em> is perimeter.
We're also told that the total perimeter is 52 inches.
We're also told that the length is six inches less than three times the width. We can express that as
.
We can plug that definition of w into the perimeter equation to find the length:
![p = 2w + 2l\\52 = 2(3l - 6) + 2 * l\\52 = 6l - 12 + 2l\\52 + 12 = 8l\\8l = 64\\l = 64/8\\l = 8](https://tex.z-dn.net/?f=p%20%3D%202w%20%2B%202l%5C%5C52%20%3D%202%283l%20-%206%29%20%2B%202%20%2A%20l%5C%5C52%20%3D%206l%20-%2012%20%2B%202l%5C%5C52%20%2B%2012%20%3D%208l%5C%5C8l%20%3D%2064%5C%5Cl%20%3D%2064%2F8%5C%5Cl%20%3D%208)
Now we can take that and the given perimeter, and substitute those into the perimeter equation to find the width:
![p = 2w + 2l\\52 = 2w + 2(8)\\52 = 2w + 16\\36 = 2w\\w = 36 / 2\\w = 18](https://tex.z-dn.net/?f=p%20%3D%202w%20%2B%202l%5C%5C52%20%3D%202w%20%2B%202%288%29%5C%5C52%20%3D%202w%20%2B%2016%5C%5C36%20%3D%202w%5C%5Cw%20%3D%2036%20%2F%202%5C%5Cw%20%3D%2018)
So the width is 18
1. 24 students and 3 absent
24-3=21
so 21 student goes
2. 21 students divided by the 3 vans
equals to 7
so 7 student went in each van
