Answer
Average cost of higher sugar prices: ${$6.67}$/person
Average cost of money directly paid to sugar growers: ${$0.50}$/person
Combined average cost: $\$7.17$/person
Work Step by Step
You can simply divide both of the amounts of money by the number of people to find the cost per person.
So, for the average cost of higher sugar prices = $\frac{$2,000,000,000}{300,000,000}$ = ${$6.67}$/person
So, for the average cost of the money directly paid to sugar growers = $\frac{$150,000,000}{300,000,000}$ = ${$0.50}$/person
Combined average cost per person:
$6.67+ $0.50 =$7.17 per person (approx).
