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