Problem B

'Temp'ting Crickets

Crickets can help determine the temperature, in degrees Celsius. One possible way to make this calculation is to follow the steps below.

Step 1: Count the number of chirps in \(25\) seconds.

Step 2: Divide the number from Step 1 by \(3\).

Step 3: Add \(4\) to the number from Step 2.

By filling in each \(\underline{\ \ \ \ \ }\) in the following equation with either a variable or a number, write an equation to show how to get the temperature, \(t\), based on a certain number of chirps, \(c\), in \(25\) seconds. \[t = \underline{\ \ \ \ \ }\div \underline{\ \ \ \ \ }+\underline{\ \ \ \ \ }\]

Fill in the second column of the following table.

Chirps (\(c\)) in \(25\) seconds Temperature (\(t\)) in degrees Celsius \(60\) \(54\) \(66\) Fill in the first column of the following table.

Chirps (\(c\)) in \(25\) seconds Temperature (\(t\)) in degrees Celsius \(18\) \(20\) \(16\)
