Answer:
1) According to the question,
[tex]1 \text{ serving has salt }= 240 \text{ mg}[/tex]
[tex]5\text{ serving has salt }= 5\times 240 \text{ mg}[/tex]
[tex]5 \text{ serving has salt } =1200\text{ mg}[/tex]
[tex]15 \text{ oz bag of chips has salt} = 1200\text{ mg}[/tex] [tex](\text{ 15 oz of salt bag contains 5 serving} )[/tex]
[tex]1 \text{ oz bag of chips has salt} = \frac{1200}{15}\text{ mg}[/tex]
[tex]1 \text{ oz bag of chips has salt} = 80 \text{ mg}[/tex]
Hence, 1 ounces of these chips has 80 mg salt.
2) [tex]1 \text{ year} = 365 \text{ day}[/tex]
[tex]1\text{ year} = 24\times 365\text{ Hours}[/tex] [tex]( \text{ 1 day = 24 hours } )[/tex]
[tex]1\text{ year} = 8760\text{ Hours}[/tex]
[tex]1\text{ year} = 60\times 8760\text{ minutes}[/tex] [tex](\text{ 1 hour = 60 minutes })[/tex]
[tex]1\text{ year} = 525600\text{ minutes}[/tex]
[tex]2\text{ year} = 2\times 525600\text{ minutes}[/tex]
[tex]2\text{ year} = 1051200\text{ minutes}[/tex]
Hence, 2 years is equal to 1 million minutes (approx)
