Question

Three ounces of broiled ground beef contains 245 calories. Is this the number of calories directly or inversely proportional to the number of ounces? Explain your reasoning and write a formula for the proportion. How many calories are there in 4 ounces of broiled hamburger?

Answer 1

Answer:

The number of calories are directly proportional to the number of ounces.

Step-by-step explanation:

We can relate these values as:

Let x be the calories in 4 ounces of broiled hamburger.

$\frac{3}{245} =\frac{4}{x}$

=> $3x=4\times245$

=> $3x=980$

Dividing by 3 on both sides;

x = 327 approx

We can see that 4 ounces contain 327 calories.

Per ounce will have $327/4=81.75$ calories.

As the quantity of hamburger increases, the calories count also increases.
