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}
