Question

The recommended daily calcium intake for a woman over 50 years of age is 1,200 mg. If one cup of milk has 295 mg of calcium, how many cups of milk provide this amount of calcium? (b) How many milliliters of milk does this correspond to?

 

Answer 1

One cup of milk has 295mg of calcium.

How many cups will provide 1200mg?

$1cup=295mg$

$??=1200mg$

$=\dfrac{1×1200}{295}$

=$4.06cups$

Equivalent to $4\ cups\ of\ milk$

Assuming one cup of milk = 250ml

$Therefore,$

$1=250ml$

$4.06=??$

$4.06*250=1015$

$=1015ml$
