    In the given question, there are two vital information's give. Firstly 8 ears of corn and 1 cantaloupe cost $2.37. On the other hand 6 ears of corn and 3 cantaloupes cost $3.51.

    Let us assume the cost of 1 corn = X

    Let us assume the cost of 1 cantaloupe = Y

    Then

    8X + Y = 2.37

    Y = 2.37 - 8X

    And

    6X + 3Y = 3.51

    Now we replace the value of Y we found from the first equation

    Then

    6X + 3 (2.37 - 8X) = 3.51

    6X - 24X + 7.11 = 3.51

    -18X = 3.51 - 7.11

    -18X = - 3.6

    X = 3.6/18

    = 0.20

    So $0.20 is the value of 1 corn. Then the value of a cantaloupe

    Y = 2.37 - 8X

    = 2.37 - (8 * 0.20)

    = 2.37 - 1.6

    = 0.77

    So cost of a cantaloupe is $0.77
