Each serving of a certain fruit snack contains 90 calories. Tyler needs some extra calories each day during his sports season. He wants to know how many servings he can have each day if all the extra calories come from the fruit snack. Write an equation that shows the number of servings, n, in terms of the number of calories, c.

(I need to know the equation for it please

An equation that shows the number of servings, n, in terms of the number of calories, c.
Calories(c) = Number of servings in grams(g) × The number of calories that a particular nutrient gives in calories per gram (Calories/gram).
Step-by-step explanation:
Calories is amount or quantity of energy which is obtainable and measurable per gram from a particular nutrient when it is injested. For example, Protein gives us 4 calories per gram, Carbohydrates gives us 4 calories per gram while from fats we have for 1 gram , we have 9 calories.
Servings can be defined as the instrument that is used to measure or a particular measurement of the amount of food we eat.
Examples of servings are: a cup, one tablespoon, e.t.c.
Servings can also be measured in grams from a weighing balance.
Therefore, an equation that shows the number of servings, n, in terms of the number of calories, c. is given as:
C = Number of servings in grams × the number of calories that a particular nutrient gives in calories per gram
For example, let us assume that tyler consumes 30 grams of rice, since rice is a carbohydrate, it is known that carbohydrate gives us 4 calories per gram
Therefore, Number of calories consumed by Tyler is = 30 grams × 4 calories per gram(calories/gram)
Number of calories = 120 calories.
