Question

ENGINEERING Tolerance in engineering is an allowance made for imperfections in a manufactured object. The manufacturer of an oven specifies a temperature tolerance of ±15ºF. This means that the temperature inside the oven will be within 15ºF of the temperature that it is set on. Write and solve an absolute value equation to find the maximum and minimum temperatures inside the oven when the thermostat is set on 400ºF.

Answer 1

Let T be the set temperature, and t the actual temperature, then |t-T|<15 (°F).

If T=400°F, then |t-400|<15, so t-400<15, making t<415°F; or 400-t<15, making 385<t.

This can be written 385°F<t<415°F.
