Volume of a Rectangular Prism Formula: V = lwh
- <em>l</em> is length
- <em>w</em> is width
- <em>h</em> is height
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify variables</em>
<em>l</em> = 4 ft
<em>w</em> = 3 ft
<em>h</em> = 9 ft
<u>Step 2: Find Volume</u>
- Substitute in variables [Volume of a Rectangular Prism Formula]: V = (4 ft)(3 ft)(9 ft)
- Evaluate [Order of Operations]: V = 108 ft³
Well you need an equation because how many friends were at the party? x*12x10=w thats your equation or however you want to put it. the letters are your variables
It would be: 420 + (420 * 17.5%)
= 420 + (420 * 0.175) [ 17.5% = 0.175 ]
= 420 + 73.5
= 493.5
In short, Your Answer would be <span>£493.5
Hope this helps!</span>

If they are looking to have them all simplified, this is how they should look.
4y - 4
4y + 4
4y + 1
