Answer:

• $6/kg
• 50 people/year

Explanation:

A unit rate is a ratio. When dollars are involved, we usually want dollars in the numerator. When time is involved, we usually want time in the denominator.

__

rice: $9/(1.5 kg) = (9/1.5) $/kg = $6/kg

__

growth: (350 people)/(7 years) = (350/7) people/year = 50 people/year
