The temperature model is (T(h)=44-2.5h). What will the temperature be at (h=10)?

Answer and explanation

Correct answer: 19

Substituting h=10 gives T(10)=44-2.5(10)=44-25=19. Therefore, 19 is the correct option. Getting 21 would be incorrect because 2.5 multiplied by 10 is 25, not 23. In exams, multiply the rate by the input first and then subtract it from the initial value.
