Answer: b is the correct option
Step-by-step explanation:
Tamara earns her living as a salary plus commission employee. This means that the total amount she earns is not fixed.
Her annual salary is $48,000. There are 12 months in a year. This means
that her her monthly salary is 48000/12 = $4000
she earns 4% commission on all sales she makes.
If Tamara wants to make a total of $6,000 this month, it means that she wants to make an extra $2000($6000-$4000) this month. She can only make this from commission based on sales
Let the sales be x
4% of x = 2000
4/100 × x = 2000
0.04x = 2000
x= 2000/0.04 = $50000
