After
his summer vacation, JimBo had $8.00 Canadian left over. He went to the bank to change his money
back into U.S. dollars. Each U.S. dollar is worth $1.33 Canadian. Order the steps JimBo takes
to determine if the solution is reasonable.
a.  Half of $8.00 is $4.00. Half of $4.00 is $2.00.
 b.  He knows that
for every Canadian dollar he receives $0.76 U.S. dollars. $0.76 is close to the fraction
3/4.  c.  So, 3/4 of $8.00
= $6.00.  d.  $6.00 is reasonable.
