Explanation:
In order to justify Marian's statement we have to look at the '' Amount per serving calories'' ⇒
In food label A we can see that this value is 160 calories
In food label B we can see that this value is 50 calories
⇒ 160 calories is slightly more than three times 50 calories
Otherwise If we want to justify Johan statement we need to look at the '' serving size '' ⇒
In food label A we can see that the serving size is 1 cup (237 mL)
In food label B we can see that the serving size is cup (56g)
Working with the information of the food label A we can write the following expression :
⇒ Looking at the value of ''
'' ⇒
If we look at the same amount of portion volume :
In cup of food A we have 40 calories
In cup of food B we have 50 calories
We could conclude that Food B has more calories.
That's how both claims could both be justified.
