Question

A salesman has a base salary of $1,400. He receives an additional 3.5% commission on his total sales. Last month his total salary was $2,800.Which equation could be solved to find the amount of his total sales?

Answer 1

$1,400+(3.5% times x)=$2,800

Answer 2

Answer:  Our required equation would be $\ 1400+(3.5\%\times x)=\ 2800$

Step-by-step explanation:

Since we have given that

Amount of salary a salesman has = $1400

Rate of commission he received = 3.5%

On last month, the total salary = $2800

Let the amount of his total sales  would be 'x'.

So, our required equation would be :

$\ 1400+(3.5\%\times x)=\ 2800$

So, if we solved the above equation , we get our required answer i.e. the amount of his total sales :

$1400+\dfrac{3.5}{100}\times x=2800\\\\0.035x=2800-1400\\\\0.035x=1400\\\\x=\dfrac{1400}{0.035}\\\\x=\ 40000$

Hence, the amount of his total sales is $40000.

Therefore, our required equation would be $\ 1400+(3.5\%\times x)=\ 2800$
