Answer:
91 grams
Step-by-step explanation:
To get a percentage you go the number which you want the percentage of divided by the full number then multiply all that by 100. For example, (10 / 100) x 100 = 10, so 10 is 10% of 100.
Now lets call the answer x:
(x / 130g) x 100 = 30%
Now you need to get x on its own, so you need to rearrange it:
x = (30 x 130) / 100
When you change the sides, you change the signs.
With this equation we can work out what 30% of 130 is. So,
(30 x 130) / 100 = 39g
So, 39g is 30%. To find out how much sugar is in the diet juice you need to subtract this from the regular cranberry juice sugar:
130 - 39 = 91g
So there is 91 grams of sugar in a serving or diet juice.
