Q. Nana is shrinking! Her height decreases by 25 mm 25 \mathrm{~mm} each year.\newlineWhat is her total change in height over 33 years?\newline____mm \mathrm{mm}
  1. Calculate annual shrinkage: Nana shrinks 25 mm25\,\text{mm} each year, so for 33 years, we just multiply 25 mm25\,\text{mm} by 33. \newline25 mm×3=75 mm25\,\text{mm} \times 3 = 75\,\text{mm}
  2. Calculate total height change: So, the total change in Nana's height over 33 years is 75 mm75\,\text{mm}.
