The income, I, for a kiddie train at an amusement park is directly proportional to the number of tickets sold, n means:


I=k*n, where k is constant


for n = 38 tickets, I = $57 that is:


57=k*38


k = 57/38


I = (57/38)n


for n = 34 tickets we have:


I = (57/38)*34


I = $51


if 34 tickets are sold the income is $51.
