logistic regression predicted values and confidence interval

#1
Hello I have run a logistic regression with two independent variables. I have used transformed my y(sales) and my x1(population) and x2(water). I have my output in excel and i'm fine with the model. What I need help with is the equation for predicting values and for getting a range of predicted values based on inputting an x1 and x2 value. Below is my output. Let say I want to predict y(sales) for the following: x1(population) = 468900 and x2(water) = 18. What would the equation and result be? What would my confidence interval be? Thank you!!
