# Problem of the Week 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.

1. 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. $t = \underline{\ \ \ \ \ }\div \underline{\ \ \ \ \ }+\underline{\ \ \ \ \ }$

2. Fill in the second column of the following table.

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

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