请问这题A哪里错呀？

问题如下：

5. If the ratio of net income to sales for a restaurant is 5 percent, what is the predicted ratio of cash flow from operations to sales?

选项：

0.007 + 0.103(5.0) = 0.524.

0.077 -0.826(5.0) =-4.054.

0.077 + 0.826(5.0) = 4.207.

解释：

C is correct.

To make a prediction using the regression model, multiply the slope coefficient by the forecast of the independent variable and add the result to the intercept.
