Okay, let's break this down step-by-step: * Randi currently pays $890 per year in property tax * Her tax is increasing by 3% * To calculate the increase, take 3% of $890: - 3% as a decimal is 0.03 - 0.03 * $890 = $26.70 * So the increase is $26.70 * To calculate what she will pay next year: - Current amount: $890 - Increase: $26.70 - Total for next year: $890 + $26.70 = $916.70 Therefore, the amount of the increase is $26.70 and the amount she will pay next
