Question

Utako sells environmentally friendly cleaning products. Her income consists of $200 per week plus a commission of 12% of her sales. Write an algebraic expression for Utako's weekly income, I, in terms of her sales, S. 
[Note: Variables are case sensitive:"I" and "i" are not the same!]

stamp · Answer

weekly income I = 200 $ + commission

commission = 12% sales = 12% S

$$I = 200 + 12\% S$$$$I = 200 + \frac{ 12 }{ 100 }S$$
