If (J(t)=100-6t), what is (J(t)) at (t=11)?
Answer and explanation
Correct answer: 34
Given \(J(t)=100-6t\). Substituting \(t=11\), \(J(11)=100-6(11)=100-66=34\). Therefore, the correct answer is 34. Getting 44 would result from an error in multiplication or subtraction. Exam tip: substitute the given value first, multiply, and then perform addition or subtraction.
