He earns $44 dollars. he charges $2 dollars for every bag.
Step-by-step explanation:
this is the answer (y2 - y1) = m (x2 - x1)
P=2(L+W)
60=P=2(L+W)
60=2(L+W)
divide by 2
30=L+W
given
W=-2+7L
subsitute
30=L+W
30=L-2+7L
30=8L-2
add 2
32=8L
divide by 8
4=L
sub back
W=-2+7L
W=-2+7(4)
W=-2+28
W=26
width is 26cm
length is 4cm
