1.3: What are the Constraints? A constraint is something that limits what is possible or reasonable in a situation. For example, one constraint in a pizza party might be the number of slices of pizza each person could have, s. We can write s < 4 to say that each person gets fewer than 4 slices. 1. Look at the expressions you wrote when planning the pizza party earlier. a. Choose an expression that uses one or more letters. b. For each letter, determine what values would be reasonable. (For instance, could the value be a non-whole number? A number greater than 50? A negativ number? Exactly 2?) 2. Write equations or inequalities that represent some constraints in your pizza party plan. If a quantity must be an exact value, use the = symbol. If it must be greater o less than a certain value to be reasonable, use the < or > symbol.
