A car salesperson earns a base salary plus commission for every car he sells. The expression shows the amount the salesperson earns, if he sells x cars in a month.
2,000 + 1,000x
If the salesman doesn't sell a car, how much money does he earn for the month?
A $0$0
B $1,000$1,000
C $2,000$2,000
D $3,000$3,000
If the salesman doesn't sell a car, the expression 2,000 + 1,000x becomes 2,000 + 1,000(0) which simplifies to 2,000 + 0.
So the salesman earns $2,000 for the month. The answer is C) $2,000.
