1. I'll get you started.

To get the \$0.70, she'll need to use one \$2.50 stamp and one \$1.20 stamp in each situation.

\$25.70 - \$3.70 = \$22.00

a) five \$4.00 stamps + two \$1.00 stamps + one \$2.50 stamps + one \$1.20 stamps

b) six \$1.00 stamps + one \$2.50 stamps + one \$1.20 stamps + ???

Must use all the \$1.00 stamps.
Therefore 25.70 - 6.00 = 19.70
The maximum number of \$4.00 stamps now useable is 4.
Therefore, 19.70 - 16 = \$3.70
Using 1 \$1.20 and 1 \$2.50 makes \$3.70.

Therefore:
6 + 1.20 + 2.50 + 16 = \$25.70
