B) $306.60

C) $318.40

D) $315.80

Answer 1

Tyler gets charged a transaction fee when he buys and when he sells.

20*$48.80=$976

20*$54.60=$1092

the cost is $1092+$976+3%*(1092+976)

3%*$2068=$62.04

Cost=$2068+$62.04=$2130.04

Sell=40*$62.80=$2512

3%*$2512=$75.36

$2512-$75.36=$2436.64

he made $2436.64-$2130.04=$306.60 which is B)
