1. A minor league baseball park has 7000 seats. Box seats cost $6, grandstand seats cost $4, and bleacher seats cost $2. When all seats are sold, the revenue is $26,400. If the number of box seats is one-third the number of
bleacher seats, how many seats of each type are there? Give a complete sentence explaining what your answers
mean.
a. Clearly define the variables in this problem.
y =
b. Write the system of linear equations for this problem.
c. Write the augmented matrix for the system of linear equations then solve using the Gauss-Jordan method.

Step-by-step explanation:

The exponential growth function is given as:

y = a(1 + r)^t

a = Initial value = 390

y = Value after time t = ?

r = Growth rate = 5% = 0.05

t = Time in years =51

Hence

y = 390(1 + 0.05)⁵¹

y = 4695.9002123

Approximately = 4695.90
