Answer:
$32,000
Step-by-step explanation:
From the information given, the equation would indicate that the total salary is equal to the base salary plus the result of subtracting $7,000 from the amount of sales for 8%:
1,000+(x-7,000)*0.08=3,000, where x is the amount of sales
Now, you can solve for x:
1,000+0.08x-560=3,000
0.08x+440=3,000
0.08x=3,000-440
x=2,560/0.08
x=32,000
According to this, the answer is that the employee must sell $32,000 in one month to earn a total of $3,000 for the month.
