CPM Homework Help : CC2 Problem 4-52

Paige traveled to Australia and is making her favorite bread recipe. She usually bakes the bread in a $350º\text{F}$ oven. She is surprised to learn that the oven temperatures in Australia are measured in degrees Celsius. In the formula at right, $F$ stands for Fahrenheit and C stands for Celsius. Use the formula and the Order of Operations to help Paige determine how she should set the oven in degrees Celsius.

$C=\frac{5(F-32)}{9}$

Hint:

You are given degrees Fahrenheit and you need degrees Celsius.

$\Large{C=\frac{5\left(\mathbf{350}-32\right)}{9}}$

Step 1:

Substitute $350º\text{F}$ for the variable $\text{F}$ . Then solve within the parentheses.

$\Large{C=\frac{\mathbf{5}\left(\mathbf{318}\right)}{9}}$

Step 2:

Simplify the numerator by multiplying.

$\Large{C=\mathbf{\frac{1590}{9}}}$

Step 3:

Divide to get your answer.
