Question

4 there are 80 calories in every 4 - ounce serving of grapes. which equation can be used to determine the number of calories, y, in x ounces of grapes? a $y = 20x$ b $y = x + 20$ c $y = 0.05x$ d $y = 84 - x$

Explanation:

Step1: Find Calories per ounce

To find the number of Calories per ounce, we divide the total Calories (80) by the number of ounces (4). So, $\frac{80}{4} = 20$. This means there are 20 Calories per ounce.

Step2: Form the equation

Since the number of Calories \( y \) is 20 times the number of ounces \( x \) (because each ounce has 20 Calories), the equation is \( y = 20x \).

Answer:

A. \( y = 20x \)
