Question

Formula:
`t = 50 + (n - 40)/(4)`Where T is temperature in Fahrenheit and N is a number of chirps per minute. If T=60°F, find the number of chirps per minute.

Answer 1

In order to find the value of N in the equation when T = 60, we just need to apply the value of T and then calculate the value of N.

So we have that:

`\begin{gathered} T=50+(N-40)/(4) \\ 60=50+(N-40)/(4) \\ (N-40)/(4)=10 \\ N-40=40 \\ N=80 \end{gathered}`

So the number of chirps per minute is 80
