In November, a toy was $40.00. In Dec., the price increased by 80%. In Jan., the price decreased by 80%. What was the price of the toy after it was discounted in January?

  • math -

    November=$40.00
    December=40.00+80%(32)=$72.00
    January=72.00-80%(57.60)=$14.40

  • math -

    November = $40.00
    December = 40.00+80%(40) = 40 + 32 = $72.00
    January=72.00-80%(72) = 72 - 57.60 = $14.40

    The work was correct, but the notation might have been confusing.
