Answer:
His total, needs to be $6000 to reach his goal.
Step-by-step explanation:
If he receives a basic salary of $800 per month, he need an extra $1200 to reach his goal of $2000 in that month. Since he receives 20% of all sales in the month he needs to make a sales of $6000 to receive a commission of $1200 to reach his goal of $2000 in that month.
Let the total sales be $x
Calculation; 20/100 * x= 1200
0.2x= 1200
X= 1200/0.2
X= $6000
