Answer:
Taking into account the values showed for this food (image attached). It is required
5
Servings.
Step-by-step explanation:
The total calcium (Cat) required is 1300 mg/day.
One serving of this food can have 260 mg.
First step is to suppose one day of calculation. t = 1 day.
Cat = (1300 mg/day)(1 day) = 1300 mg Calcium.
One single serving can have 260 mg Calcium (Cas). So, we need to calculate the amount of servings (N) required to complete 1300 mg.
Cat = Cas*N
N = Cat/Cas = 1300 mg/260mg
N = 5.
Finally amount of servings is five N = 5.
