It is -10°F now. School is canceled when the temperature is colder than -5°F. Describe how much the temperature can increase before school will reopen using the inequality -10 + x < -5. Which choice shows the correct solution and conclusion?
A. x < 5, so the increase must be less than 5°F or there will be school.
B. x > 5, so the increase must be more than 5°F or there will be school.
C. x < -15, so the increase must be less than -15°F or there will be school.
D. x < 5, so the temperature must be less than 5°F or there will be school.
