Nd a company gives each new salesperson a commission of $300 for the sale of a new car. the salesperson will receive a $100 increase for each addition car the person sells that week, so the person gets $400 for the next sale that week. which equation can find the number of cars a salesperson must sell to earn $4,200 in a week? recall that a1/d(n-1) is equivalent to an

General Idea:

In an arithmetic sequence, to find the term, we need to use the below formula:

Here gives the term

gives the first term of sequence

d is the common difference and n is the number of terms in the sequence.

Applying the concept:

In our problem it is given that "A company gives each new salesperson a commission of $300 for the sale of a new car",

so

"The salesperson will receive a $100 increase for each addition car the person sells that week"

so

"find the number of cars a salesperson must sell to earn $4,200 in a week", this means that we need to find the value of n, when

Setting up the equation based on the arithmetic sequence formula, we get:

Conclusion:

New Salesperson has to sell 40 cars to earn $4200 in a week.

you answer is a

step-by-step explanation:

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
