The answer would be 10 it is cheaper you must divide here is my work
<span>You divide unit per price = 10/$6.75 = $1.48
12/$7.25 = $1.65
Which means 10 units are cheaper</span>

Answer: 4(x - 1)(x^2 + x + 1)</h3>
==================================================
Work Shown:
4x^3 - 4
4(x^3 - 1)
4(x - 1)(x^2 + x + 1)
In the last step, I used the difference of cubes factoring formula which is
a^3 - b^3 = (a - b)(a^2 + ab + b^2)
1. 343^(2/3)
3rdrt[(343(343)]
49
2. [2,197^(1/3)]^2
[3rdrt(2,197)]^2
169
3. 729^(2/3)
3rdrt[729(729)]
81
4. (1,000^2)^(1/3)
3rdrt(1,000^2)
100
5. [3rdrt(9261)]^2
441
6. [3rdrt(216^2)]
36
Hope this helps!

RS = 6
TR = 4.5
Find TS.
R--------------T----------------S
TS = RS - TR
TS = 6 - 4.5
TS = 1.5
