Question

40% of the calories in a bag of chips come from fat. If 100 calories come from fat, how many calories does the whole bag of chips contain?

Answer 1

250

Explanation:

Let x be the total amount of calories the bag bag of chirps contains.

From the question it can be deduced that, 40% of the calories that come from fat is 100.

This implies

`(40)/(100) * x = 100`

Multiply through by 100.

`\implies (40x)/(100) * 100 = 100 * 100`

`\implies40x = 10000`

Divide through by 40.

`\implies (40x)/(40) = (10000)/(40)`

`\implies x = 250`

Thus, the whole bag of chips contains 250 calories
