Race track a has 37,000 more grandstand seats than three times the number of grandstand seats at another race track b. together, these two race tracks seat 289,000 auto racing fans. how many seats does each race track have

Let x represent the number of grandstand seats on race track #2

The number of grandstand seats on race track #1 =  37,000 + 3x

Total number of seats together = 289,000

So, we can frame the equation as follows:

37,000 + 3x + x = 289,000

4x + 37,000 = 289,000

4x = 289,000-37,000 = 252,000

4x = 252,000

x = 252,000/4

x = 63,000

Number of seats on race track #2= x = 63,000 seats

Number of seats on race track #1 = 37000+3x = 37000+3*63000 = 226,000 seats

investment b is an ordinary annuity with $3,909.64 in the account after one year.
