Determine pattern: Determine the pattern of the increase in the number of seats per row. We are given the number of seats in the first five rows: 10, 15, 17, 22, 24. We need to find the pattern of increase to determine the number of seats in the remaining rows. From row 1 to row 2, the increase is 5 seats (15 - 10). From row 2 to row 3, the increase is 2 seats (17 - 15). From row 3 to row 4, the increase is 5 seats (22 - 17). From row 4 to row 5, the increase is 2 seats (24 - 22). It seems that the pattern is an alternating increase of 5 and 2 seats.Calculate seats per row: Calculate the number of seats in each of the remaining rows. Using the pattern from Step 1, we can determine the number of seats in rows 6 to 9. Row 6: 24 (previous row) + 5 (increase) = 29 seats Row 7: 29 (previous row) + 2 (increase) = 31 seats Row 8: 31 (previous row) + 5 (increase) = 36 seats Row 9: 36 (previous row) + 2 (increase) = 38 seatsTotal seats calculation: Calculate the total number of seats in the theater. We add the number of seats from all rows to find the total capacity. Total seats = 10 (row 1) + 15 (row 2) + 17 (row 3) + 22 (row 4) + 24 (row 5) + 29 (row 6) + 31 (row 7) + 36 (row 8) + 38 (row 9) Total seats = 222Calculate filled seats: Calculate the number of seats filled during the performance. Since only half of the total capacity is filled, we divide the total number of seats by 2. Seats filled = 222 / 2 Seats filled = 111Total revenue calculation: Calculate the total revenue from the performance. We multiply the number of seats filled by the price per ticket to find the total revenue. Total revenue = Seats filled * Price per ticket Total revenue = 111 * Rp. 50,000 Total revenue = Rp. 5,550,000
