A certain concert venue has a total of 500 seats, some of which are premium seats near the stage, with the rest of the seats being standard seats further away from the stage. Premium seats at this venue cost $30, while standard seats at this venue cost $21. At the last concert, a total of $11,616 were collected in seat revenue. Assuming all 500 seats were filled, how many of each type of seat was purchased?

5   1/4   miles per hour

step-by-step explanation:

15   3/4 / 3 = 5   1/4

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100

step-by-step explanation:

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
