Answer:
115
Step-by-step explanation:
You solve this by factoring.
12140 = x^2-10x+65
0 = x^2-10x-12075
0=(x+105)(x-115)
The only positive solution is x=115
Let X describes the sales
350.25+0.12x=800.5
Now solve for x
0.12x=800.5-350.25
0.12x=450.25
X=450.25÷0.12
X=3,752.08
the sales necessary for the salesperson to earn at least $800.50 in one week is 3,752.08
Answer:
(3960+4090+3200+3100+2940+3830+4090+4040+3780)/9 = 33030/9 = 3670
