A nutritionist established a significant relationship among the fat content, the amount of carbohydrates, and the number of calories in a variety of popular 1-ounce snacks. She obtained the regression equation y’ = 10.954 + 8.4987x₁ + 4.2982x₂, where y is the number of calories per snack, x₁ is the number of grams of fat and x₂ represents the number of carbohydrates in grams. Predict the number of calories in a snack which contains 10 g of fat and 19 g of carbohydrates.
