You are buying beads and string to make a necklace. The string costs $1.50, a package of 10 decorative beads costs $.50, and a package of 25 plain beads costs $.75. You can spend only $7.00 and you need 150 beads. How many packages of each type of bead should you buy?

ok, you have 5.50 to spend on beads.

D*.50+P*.75=5.5

10D+25P=150

can you solve it?
