stock on his broker's advice and paid his broker a 1% broker fee.

Part A

Write an expression to model Samantha's net proceeds algebraically. Explain how

you determined the expression.

Answer 1

Net proceed= s-0.98nd-11

Explanation:

Given that the shares cost $d

n shares will be =$dn

paid 2% commission to her broker= (2/100)*nd= 0.02nd

sold the share for $s
