Answer 1

96 ounces

Step-by-step explanation:

Given that:

There are 1.5 mg of the iron present in 8 ounces of the apple juice.

So,

There are 1 mg of the iron present in
`\frac {8}{1.5}` ounces of the apple juice.

Also,

18 mg of the iron is required for RDA. So, number of ounces that contains the RDA are:

There are 18 mg of the iron present in
`\frac {8}{1.5}* 18` ounces of the apple juice.

Number of ounces = 96 ounces
