Full solution

Q. Betty had 100100 muffins in the morning.\newlineShe gave away some muffins.\newlineShe baked another 3535 muffins in the afternoon and sold all 8080 muffins she had.\newlineHow many muffins did she give away?
  1. Given Information: Given: Betty initially had 100100 muffins.\newlineShe gave away an unknown number of muffins, let's call this number GG.\newlineShe then baked 3535 more muffins.\newlineAfterwards, she sold all 8080 muffins she had left.\newlineWe need to find the value of GG.
  2. Calculate Total Muffins: Calculate the total number of muffins Betty had after baking more.\newlineInitial muffins = 100100\newlineMuffins baked = 3535\newlineTotal muffins after baking = 100+35100 + 35\newlineTotal muffins after baking = 135135
  3. Find Muffins Given Away: Use the information that Betty sold 8080 muffins to find out how many she gave away.\newlineTotal muffins after baking = 135135\newlineMuffins sold = 8080\newlineMuffins given away = Total muffins after baking - Muffins sold\newlineMuffins given away = 13580135 - 80\newlineMuffins given away = 5555
