Question

you are preheating an oven to 350 degrees Fahrenheit before you bake muffins. several minutes later, the oven thermometer reads 346 degrees Fahrenheit. the measured temperature has an absolute deviation of at most 2 degrees Fahrenheit. write and solve an inequality to find the possible temperatures in the oven. should you continue to preheat the oven, or should you start baking the muffins?

Answer 1

|T-346| <= 2
344 <= T <= 348
so, keep heating.
