    Answer:

    The expression given by Ivy is WRONG.

    The correct expression is  $(19 + 77 x (0.5) )

    The total mount in jar = $57.5

    Step-by-step explanation:

    Here, for each point scored, $0.5 is put in the jar.

    Now, the point scored in the first game  = 38 points

    So, the amount put in the jar for 38 points = 38 x ( amount for 1 point)

    =  38 x ( $0.5)   = $19

    So, after first game, jar has $19.

    Now, the point scored in the(2 +3) game  = 77 points

    So, the amount put in the jar for 77 points = 77 x ( amount for 1 point)

    =  77 x ( $0.5)   = 77 x (0.5)

    So, after second and third  game, jar has $ (77 x (0.5)).

    Now, total amount in jar  

    = Amount after first game  + Amount after second and third game

    = 19 + 77 x (0.5)

    But , here THE TOTAL AMOUNT given by Ivy  = 38+(77  x 0.5)

    And 19 + 77 x (0.5)  ≠ 38+(77  x 0.5)

    Hence, the expression given by Ivy is WRONG.

    The correct expression is  $(19 + 77 x (0.5) )

    And, the total mount in jar = 19 +  38.5 =  $57.5
