You can put this solution on YOUR website!
1 American dollar = 1.25 Martian dollar
Divide both sides by 1.25
( 1/1.25 ) American dollar = ( 1.25/1.25 ) Martian dollar
.8 American dollar = 1 Martian dollar
Multiply both sides by 100
80 American dollars = 100 Martian dollars
Molly spent 80 American dollars
