30 grams of a breakfast cereal provides 16.2mg of vitamin C. This is 24% of the recommended daily intake. What daily intake of vitamin C is recommended?
.24x = 16.2
To find the recommended daily intake of vitamin C, we need to calculate the value corresponding to 100%.
First, we need to determine the amount of vitamin C in 100% of the recommended daily intake.
Since 30 grams of cereal provides 16.2mg of vitamin C, we can set up the following proportion:
30 grams = 16.2mg
100% = x
To find x (the amount of vitamin C in 100% of the recommended daily intake), we cross-multiply and solve for x:
30 * x = 100 * 16.2
30x = 1620
x = 1620 / 30
x = 54
Therefore, 54mg is the recommended daily intake of vitamin C.
