Let
x = base pay per month
y = commission per $1 of sales
Then the monthly pay for selling $100 of merchandise is
P = x + 100y
In one month, Alyssa earned $388 for selling $400 worth of merchandise.
Therefore
x + 400y = 388 (1)
In another month, she earned $520 for selling $1000 worth of merchandise.
Therefore
x + 1000y = 520 (2)
Subtract (1) from (2).
x + 1000y - (x + 400y) = 520 - 388
600y = 132
y = 0.22
From (1), obtain
x = 388 - 400y = 388 - 400*0.22 = 300
When Alyssa sells $3300 worth of merchandise, she earns
300 +0.22*3300 = $1026
Answer: $1026
now, bear in mind, that zeroing out the denominator, also gives critical points, usually asymptotic points, where the derivative is undefined, now, in this case, the denominator is never zero, so we don't get any from the denominator, just from the numerator, and are 0 and 1
now check the picture below
running a first-derivative test on it, those are the values on those regions
you get a negative, regardless of what it might be, what matters is the sign
you get a positive, and then a negative
so, f(x) goes down, then up then down
now, you can see, there's on relative minimum and a relative maximum
