Question

The admission fee at an amusement park is $3.25 for children and $5.40 for adults. On a certain day, 280 people entered the park, and the admission fees collected totaled 1254 dollars. How many children and how many adults were admitted?

Answer 1

3.25C + 5.40A = 1254

C+A = 280,

C=280-A

3.25(280-A) + 5.4A = 1254

2.15A = 344

A = 160 adults

C 280-160 = 120 children
