Alexa pays $13.50

Step-by-step explanation:

1. find 40% of each item cost

($5 = 100%) /5 = ($1 = 20%) *2 = $2 = 40%($15 = 100%) /5 = ($3 = 20%) *2 = $6 = 40%($2.50 = 100%) /5 = ($0.50 = 20%) *2 = $1 = 40%

2. find cost of each item

$5 - $2 = $3$15 - $6 = $9$2.50 - $1 = $1.50

3. find total cost

$3 + $9 + $1.50 = $13.50

Let w width and l length.

3(2(l+w))= lw

6l+6w=lw

6l=lw-6w

w(l-6)=6l

w=6l/(l-6)

the smallest perimeter = 2( l+ 6l/(l-6))
