Total cost is $38.16
Multiply 36 by 0.06 (2.16)
Add 2.16 to 36 (38.16)
Well, there are different ways to do this if you are really familiar with fractions, but "officially" :P
1) convert mixed numbers to improper fractions.
rule: a b/c = (ac+b)/c
2) make all fractions have a common denominator...
a/b+c/d
(a/b)(d/d)+(c/d)(b/b)
(ad/bd)+(cb/bd)
3)
The simplify your final answer with greatest common denominator or convert back to mixed number if needed...
Step-by-step explanation:
To transform a function vertically, add 3 to the constant.

So the function is

Graph the function in desmos to show the translation vertically if you want proof
2(4-d+2d)=12
8-2d+4d=12
8+2d=12
2d=4
d=2
