Answer:

£3,780

Step-by-step explanation:

Total rows = 19 rows

Seats per row = 28 seats

Cost of tickets per seats = £8.75

Total number of seats at the concert = Total rows × seats per row

= 19 rows × 28 seats

= 532 seats

The tickets for 100 seats have not been sold

Total number of tickets = sold tickets + unsold tickets

532 = sold tickets + 100

532 - 100 = sold tickets

432 = sold tickets

Sold tickets = 432 tickets

Total cost estimate of sold tickets = sold tickets × cost of tickets per seats

= 432 × £8.75

= £3,780

Mila [183]

Question is Incomplete, Complete Question is given below.

A piano teacher has 4 1/2 hours available to teach in a night each lesson the last 1 1/2 hours how many lessons can the teacher schedule in a night.

Answer:

The Piano teacher can teach 3 lessons in night.

Step-by-step explanation:

Given:

Number of Hours Available = $4\frac{1}{2} \ hrs$

$4\frac{1}{2} \ hrs$ can be Rewritten as $\frac{9}{2} \ hrs$

Number of hours for Each Lessons = $1\frac{1}{2} \ hrs$

$1\frac{1}{2} \ hrs$ can be Rewritten as $\frac{3}{2} \ hrs$

We need to find Number of lesson that can be scheduled for night.

Number of lesson scheduled for night can be calculated by dividing number of hours available in night with number of hours each lesson would required.

Framing above sentence in equation form we get;

Number of lesson scheduled for night = $\frac{\textrm{Number of Hours Available}}{\textrm{Number of hours for Each Lessons}}$

Substituting the values we get;

Number of lesson scheduled for night = $\frac{\frac{9}{2}}{\frac{3}{2}} = \frac{9\times2}{3\times2}=\frac{18}{6} =3$

Hence The Piano teacher can teach 3 lessons in night.
