Kathy's monthly salary is $3,250, plus she earns 1.4% commission on her sales each month. Kathy's sales for September were $51,000. What were her total earnings for September?

Step-by-step explanation:

We can start off by putting this into an equation. Kalil's monthly salary is not a changing value, so that stays put. However, any additional money he gets from selling his stuff, he gets to keep 1.4%.

Thus, we can just add his salary and his commission earnings.

To find the commission, we just multiply 1.4% by $51,000 (the total sales, not his salary).

Thus, Kalil got $3964 in July.

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
