Mary has a pretzel booth at the county fair. Soft and salty pretzels are her specialty. Mary measured her supply of salt to sprinkle on the pretzels and found that she had 11 cups to use during the week. If Mary has 2 cups of salt remaining to make the pretzels on Friday, she will not need to go the market. Mary thinks that she has enough salt for the pretzels on Friday. On Monday, Mary used 3 ¾ cups of salt. On Tuesday, she used 1 ¾ cups of salt. She used 2 ¼ cups of salt on Wednesday and 1 ¾ cups of salt on Thursday. Do you think Mary is right or wrong that she has at least 2 cups of salt to use on Friday without going to the market? Explain why you think Mary is right or wrong. Include a model and addition and/or subtraction equations in your explanation. The Salty Pretzels Task
