Answer:
Domain { 0 ≤ r≤ 18}
Range = {0≤ c ≤ 31.5}
Step-by-step explanation:
The domain is the values that r can take
He can goes on each ride up to 1 time
R can be from 0 rides to 18 rides since there are only 18 rides
Domain { 0 ≤ r≤ 18}
The range is the output
If r = 0 then he spends no money
if r =18 then 1.75*18 =31.5
Range = {0≤ C(r) ≤ 31.5}
Let's find the required ratios first: to get to the relative percentages, we'll simply have to multiply by 100.
Since there are 16 girls, 10 boys and 9 adults, there are

people in total.
So, the ratio of girls is

The ratio of boys is

The ratio of adults is

X is equivalent to 200. (credit to suspho)
