Which function could be used to determine the total cost, t, for the English class to attend the performance?

Question

An English class attended a performance at the theater. The class took 25 students and 3 adults. Each student ticket, s, cost $3 less than an adult ticket. Which function could be used to determine the total cost, t, for the English class to attend the performance?

Answer 1

s = a - 3

 

t = 25s + 3a

 

t = 25(a - 3) + 3a

t = 25a - 75 + 3a

t = 28a - 75
