Question

A​ low-calorie bread has 98 calories in a 2​-slice serving. This is 10​% fewer than the number of calories in a serving of regular bread. How many calories are in the same size serving of regular​ bread?

Answer 1

`~~109` calories

Explanation:

Well, if `98` calories is `10%` lower than the number of calories in a serving of regular bread, that must mean that, `98` calories is `90%` of the calories in normal bread.

Let the number of calories in regular bread be `x`.

`:.90%x=98`

`9/10x=98`

`:.x=98*10/9=108.88...`

Now, we can round it to the nearest whole number.

`108.88...~~109`

So, regular bread has around `109` calories.
