Maria had $100 to go shopping for some new clothes. She bought two shirts that each cost $8.95, jeans that were $24.97, and a set of shoes. The cashier gave Maria $16.27 back after she paid for everything. How much were the shoes?
An equation that describes this problem would be 100 - 2(8.95) - 24.97 - ____ = 16.27. Once you subtract the shirts and jeans from Maria's total, she has $57.13 left. We know that she bought shoes, and still had $16.27 left over, so 57.13 - 16.27 = 40.86. The shoes cost $40.86

Alex and Emma both went trick-or-treating in their neighborhoods. The amount of candy Alex collected is represented by the equation 3x - 2y = 18. Emma collected candy at a rate of y = x + 12, where x represents the number of minutes spent trick-or-treating. How many minutes will it take for Alex and Emma to have the same amount of candy?
42 minutes. They will both have 54 pieces of candy at that time.
