Nadia is a stockbroker. She earns 11% commission each week. Last week, she sold $7,000 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?

Nadia's commission per week is $770

Amount Nadia made in commission in 2011 is $40,040

Step-by-step explanation:

Commission made last week = 11% of $7,000

Therefore commission made last week = 0.11 × $7,000 = $770

Whereby Nadia averages the same aount each week, the amount Nadia would make in commission in 2011 is given by

Amount Nadia makes per week in commission = $7,000

Number of weeks in a year = 52 weeks. Therefore, amount Nadia makes in one year is given by

Amount in commission per week × 52 weeks

=$770 × 52 = $40,040

Amount Nadia made in 2011 = $40,040.

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
