Question

The recommended dietary allowance for calcium for teenage children is 1,300 mg per day.

Answer 1

Answer:

c) 35 fl oz

Explanation:

Hello,

In this case, to compute the recommended amount of calcium that the teenager must drink, one performs the following relationship:

$8.0-fl \ oz -->298mg\\x-->1,300mg$

Solving for $x$, one gets:

$x=\frac{8.0-fl \ oz *1,300mg}{298mg} \\x=35-fl \ oz$

Best regards.
