    Answer:

    Step-by-step explanation:

    Let us represent

    Let the wood bat = w

    Let the base ball bats = b

    Savelot offers two types of baseballs bats the wood bat sell for 24$ and the metal bats sell for 30 in one day save lots sold 23 base ball bats these recipts for those bats totaled $606 how many of each type of bat was sold

    System of Equations

    w + b = 23…. Equation 1

    b = 23 – w

    24w + 30b = 606….. Equation 2

    We substitute:30 – w for b

    Hence:

    24w + 30(23 – w) = 606

    24w + 690 – 30w = 606

    24w – 30w = 606 – 609

    -6w = -84

    w = -844/-6

    w = 14 wood bats

    b = 30 – 14

    b = 16 base ball bts
