Answer:
309
Step-by-step explanation:
8x + 300 = 2772
subtract 300 from both sides of the equal sign
8x = 2472
divide 8 from both sides of the equal sign
x = 309
The total no. of seats that have been sold is 309
What are linear equalities in one variable?
The linear equation in one variable is an equation that is expressed within the form of ax+b = zero, where a and b are integers, and x is a variable and has only one answer.
Conclusion: For example, 2x+3=8 is a linear equation having a single variable in it. therefore, this equation has only one solution, which is x = 5/2.
let the auditorium sell x seats for 8 dollars per seat.
In addition to that auditorium made 300 dollars.
The total money earned by the auditorium by selling x seats and the addition of 300 dollars is 2772 dollars.
8x + 300 = 2772
8x = 2772 - 300
8x = 2472
x = 2472/ 8
x = 309
