Question

18. 54 grams of a certain brand of breakfast cereal contain 190 calories. Let g

represent grams of cereal and c represent calories. Identify the type of variation,
find the constant, and write an equation to represent the relationship between
grams and calories.

Answer 1

The relation is c = 3.519g.

Explanation:

This is direct variation.

c = kg where k is the constant of variation.

Substituting the given values:

190 = k * 54

so the constant of variation is:

k = 190/54 = 3.519 to nearest thousandth,

and the equation is:

c = 3.519g.
