A nutritionist is creating a meal plan that combines two types of food, A and B, to meet a specific protein target. Food A contains 15 grams of protein per serving, and Food B contains 25 grams of protein per serving. The equation represents the total protein, in grams, from servings of Food A and servings of Food B. If a person only consumes Food A to meet the 300-gram protein target, how many servings of Food A would they need?
