Answer:
B, the square root of 3
Step-by-step explanation:
5 big cubes 4 longs and 2 small cubes
A: cost= 3*55+.35m
B: cost=3*50+.40m
set the costs equal, and solve for m.
(25,000+4x)/5=<span>18,600
</span><span>25,000+<span>4x</span></span>=<span>93,000 (multiply both sides by 5)
</span><span>4x</span>=<span>68,000 (subtract 25,000 from both sides)
</span>x=<span>17,000 (divide both sides by 4)

The equation is
8x +7=125
