Nadia is a stockbroker. She earns 11% commission each week. Last week, she sold $5,400 worth of stocks. How much did she make last week in commission? If she averages that same amount each week, how much did she make in commission in 2011?

Step-by-step explanation:

C=0.11×5,400=594

Nadia made a total of $594 last week in commission sales

b). To express the total amount she made in 2011, we derive the formula below;

Total amount (2011)=Average weekly commission× number of weeks in 2011

where;

Average weekly commission=$594

number of weeks in 2011=52

replacing;

Total amount (2011)=(594×52)=30,888

The total amount Nadia in commission in 2011=$30,888

answer: she must produce at least 9,000 windows in order to make a profit of $48,000

explanation:

48,000 - 12,000 = 36,000

36,000/4 = 9,000
