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?

  • algebra -

    150=D+P
    7=1.50+10D*.5+24P*.75

    can you do it from that?
