My question is: Lisa was collecting socks to donate to a homeless shelter. She bought 12 pairs at a discount store. Sandra, her friend, came over and brought her 20 pairs of socks. Her cousin showed up with one-fifth the number of pairs that Sandra bought. After work, Lisa's mom brought 8 more than three times the number of pairs Lisa started with. How many pairs of socks did Lisa end up with? Your thoughts:
Her cousin brought over 20 / 5 = 4 pairs of socks. Three times more than Lisa bought was 12 * 3 = 36. Her mom brought 36 + 8 = 44 pairs of socks. In total Lisa had 12 + 20 + 4 + 44 = 80 pairs of socks. The final answer: 80.
