Jade is building a lego tower. She has 100 pieces. Each level has to be 7 pieces wide. If she has 23 pieces left at the end, how many levels is her tower?
How many legos did Jade use? ** She used 77 legos because 100 - 23 = <<100-23=77>>77
How many levels did Jade make? ** She made 11 levels because 77 / 7 = <<77/7=11>>11
