In a pepper airplane contest, amanda's plane flew 19ft farther than darren's plane. darren's plane flew twice as far as rachel's plane. rachael's plane flew 20ft. how far did amanda's plane fly?

Amanda's plane flew 59ft

Step-by-step explanation:

So you make simple formulas for this A= Amanda D= Darren and R= Rachel

Darren's is twice as far as Rachel's so D=2R

Amanda's when 19 more feet than Darren's so A=D+19

Then you plug in, you know R=20

D=2R          D=2*20     D=40

A=D+19      A=40+19    A=59

total amount of money that he should pay if he has not used his duty free exemption is $98
