Answer:
(-b±√(b²-4ac))/(2a)
where,
ax²+bx+c=0
a, b, c = constants, where a ≠ 0
x = the unknown
Step-by-step explanation:
His total sales were "x"
now, we know that 3.5% of "x" plus 5% of "x", will add up to his total commission, including sales of 6500 or less or more
so the commission for 6500 or less, is 3.5% of "x" or (3.5/100)*x -> 0.035x
the commission for above 6500 is 5% or (5/100) * x --> 0.05x
we know, that both commissions added together, are $415
thus
0.035x + 0.05x = 415 <----- solve for "x"
Answer:
1,686,000
Step-by-step explanation:
The answer is D, i.e. the system was solved via elimination
If you multiply the first equation by 5, the system becomes
If you sum the two equations, you get
And so if you substitute the second equation of system A with this new equation, you'll get system B.
Answer:
52
Step-by-step explanation:
